I spent some time manually editing a post replacing Mathematica ASCII \[Alpha] with Unicode α. I did this by laboriously choosing Copy as LaTeX, pasting into the edit box, and then copying the Unicode symbol from the preview below. This made me realize I am lacking a "Copy as Unicode string" function in Mathematica.
How can I most easily copy an expression such as:
In Unicode:
αβ + Mod[δΨ, 2 ρ^2]
Since a native method is not forthcoming, I shall post my file based circumvention, for Windows.
You will need to have this utility in the command path (it apparently is stock with Windows 7).
copyUnicode[expr_] := Run["clip <",
Export["$Clipboard.temp", ToString[expr, InputForm],
"Text", CharacterEncoding -> "Unicode"] ];
Usage:
expr = \[Alpha]\[Beta] + Mod[\[Delta]\[CapitalPsi], 2\[InvisibleTimes]\[Rho]^2];
copyUnicode[expr]
This leaves the following text in the Windows Clipboard:
αβ + Mod[δΨ, 2*ρ^2]
Here is a version of the function that holds (does not evaluate) the expression:
SetAttributes[copyUnicode, HoldFirst]
copyUnicode[expr_, form_: InputForm] :=
Run["clip <",
Export["$Clipboard.temp", ToString[Unevaluated@expr, form], "Text",
CharacterEncoding -> "Unicode"]];
Now:
Plot[\[Alpha], {\[Alpha], 0, 10}] // copyUnicode
Puts in the Windows Clipboard:
Plot[α, {α, 0, 10}]
This method for Windows is based on the .NET code from Todd Gayley's this wonderful answer. My .NET knowledge is absolutely ZERO, all credit goes to Todd.
The main idea is to extract the "Input"-style code string, convert it to the UTF-16 little endian form, which is the standard byte order in Windows, feed the bytes to system clipboard by using .NET API.
The main functions are placed in a package:
Needs["NETLink`"]
InstallNET[];
BeginPackage["UniCodeCopy`"]
mmaUnicodeToUTF16LE::usage =
ToString[Row[{Style["mmaUnicodeToUTF16LE[_Integer]", Bold], " convert integer list obtained from ", Style[Row[{"ToCharacterCode[", Style["string", Italic], ", "Unicode"]"}], Bold], " to integer list consistent with the UTF‐16 Little Endian standard."}], StandardForm];
stringToUTF16LE::usage =
ToString[Row[{Style["stringToUTF16LE[_String]", Bold], " convert ", Style["string", Italic], " to integer list consistent with the UTF‐16 Little Endian standard."}], StandardForm];
WriteToClipboardUnicode::usage =
ToString[Row[{Style["WriteToClipboardUnicode[_String]", Bold], " write ", Style["string", Italic], " to Windows clipboard using the UTF‐16 Little Endian encoding."}], StandardForm];
Begin["Private"]
Clear[mmaUnicodeToUTF16LE]
mmaUnicodeToUTF16LE[bytecode_Integer] :=
PadRight[#, 2 Ceiling[Length@#/2]] &@
Join[Most[#] - Rest[# 2^8], #[[{-1}]]] &@
DeleteCases[FixedPointList[BitShiftRight[#, 8] &, bytecode], 0]
Clear[stringToUTF16LE]
stringToUTF16LE[str_String] :=
mmaUnicodeToUTF16LE /@ ToCharacterCode[str, "Unicode"] //
Flatten // Join[#, {0, 0}] &
Clear[WriteToClipboardUnicode]
WriteToClipboardUnicode[str_String] :=
Module[{bytecode, strm, dataObject},
bytecode = stringToUTF16LE[str];
NETLinkNETBlock[ strm = NETLinkNETNew["System.IO.MemoryStream", bytecode];
dataObject = NETLinkNETNew["System.Windows.Forms.DataObject"]; dataObject@NETLinkSetData["Text", strm];
NETLinkLoadNETType["System.Windows.Forms.Clipboard"]; SystemWindowsFormsClipboard`SetDataObject[dataObject]
]
]
End[]
EndPackage[]
Then execute the following code, which will generate a palette with a UniCode Copy button:
Button["UniCode Copy",
Module[{codestr},
timestamp = {};
FrontEndExecute[FrontEndToken["CopySpecial", "InputText"]];
codestr =
NotebookGet[ClipboardNotebook[]][[1, 1, 1]] //
StringReplace[#, {"\\\n" -> "",
"\n" ~~ space : " " ... :>
StringJoin["\n", ConstantArray[space, 4]]}] &;
UniCodeCopy`WriteToClipboardUnicode[codestr]
],
Method -> "Queued"
]
SelectionMove[EvaluationNotebook[], Previous, Cell];
FrontEndExecute[FrontEndToken["GeneratePalette"]];
FrontEndExecute[FrontEndToken["Clear"]];
To use it, select the Cells you want to copy as input text code, then press the button. The package can be put in a file and be auto-loaded when MMA start, the palette can be installed to system menu.

\[Transpose]), convert the corresponding parts into InputForm(how?), then make the copy.

copyUnicode (with or without a Hold attribute) as I have been doing. If it were platform and version independent I would have Accepted it, but I did not so as to leave room for future additions.

\[Rule] cannot be converted into unicode. Does that mean there is no such a corresponding symbol there?
– LCFactorization
Feb 14 '16 at 09:11
\[Rule] symbol in MMA, whose Unicode is U+F522, is in the Basic Multilingual Plane (U+E000–U+F8FF), one of the Private Use Area in Unicode standard, thus may not be printable in 3rd party software.

Edit 2: A new version of the Mac solution with button is listed below
Fixed problem with pasting into textarea
In some applications on Mac, copying as Unicode from Mathematica already works without having to do any postprocessing. However, it doesn't work in textarea fields in web browsers.
Nevertheless, if you're willing to do a few additional mouse clicks, the Unicode forms can be brought into the browser by taking the detour through one of those applications that do support Mathematica's characters. One convenient choice is to open a new window in TextEdit and paste your original Mathematica code into it first. In the default RichText mode, TextEdit displays the special characters as Unicode glyphs. Then you can simply copy whatever you just pasted back from TextEdit and paste it into the browser. It seems that as soon as TextEdit is recognized as the provider of the Unicode text on the pasteboard, there is no conversion back to the Mathematica representation, so you get the correct appearance in the browser.
In the following, I use the same idea in order to automate the conversion. Instead of TextEdit, I go through a temporary file in RichText (RTF) format on the provider side. The Mac pasteboard does support RTF as a format for data on the pasteboard, but this isn't accepted by the browsers I've recently tried when attempting to paste into textarea.
Therefore, I have to add one additional step: using the textutil tool which is built into OS X, I convert the RTF file to a regular text file with Unicode characters first. Then I read the text file back in and put it on the pasteboard.
Of course, this means it's only going to work on Mac OS X because it uses Cocoa bindings in the built-in Python interpreter:
copyAsUnicode[t_] :=
Module[{out =
FileNameJoin[{$TemporaryDirectory,
"MathematicaOutput" <> StringJoin[Map[ToString, DateList[]]]}]},
Export[out <> ".rtf", t];
Run["textutil -convert txt " <> out <> ".rtf -output " <> out <>
".txt"];
Run["printf \"from AppKit import *\n\
board=NSPasteboard.generalPasteboard()\n\
content=NSData.dataWithContentsOfFile_('" <> out <>
".txt')\nboard.declareTypes_owner_([NSStringPboardType], None)\n\
board.setData_forType_(content, NSStringPboardType)\n\
\" | /usr/bin/python"];
DeleteFile[{out <> ".txt", out <> ".rtf"}]]
The idea is to export to RTF and read the result to the clipboard outside of Mathematica. The function is invoked for example as copyAsUnicode["αβ+Mod[δΨ+ρ2]"]. This example itself was copied that way, too, i.e., I typed copyAsUnicode["copyAsUnicode[\"αβ+Mod[δΨ+ρ2]\"]"], which I again copied the same way... OK, I think you get the idea.
Of course the next step would be to make this into a Palette that acts on the NotebookSelection, but the above is the main step. Maybe someone else knows how to do something like this in other operating systems (I don't).
Installing this function as a button:
Responding to the comment, here I'm just listing the same function as above, but wrapped in Silvia's code to make it into a button. It requires no package loading because I inlined everything into the button code:
Button["UniCode Copy", Module[{codestr},
FrontEndExecute[FrontEndToken["CopySpecial", "InputText"]];
codestr = NotebookGet[ClipboardNotebook[]][[1, 1, 1]];
Module[{out =
FileNameJoin[{$TemporaryDirectory,
"MathematicaOutput" <> StringJoin[Map[ToString, DateList[]]]}]},
Export[out <> ".rtf", codestr];
Run["textutil -convert txt " <> out <> ".rtf -output " <> out <>
".txt"];
Run["printf \"from AppKit import *\n\
board=NSPasteboard.generalPasteboard()\n\
content=NSData.dataWithContentsOfFile_('" <> out <>
".txt')\nboard.declareTypes_owner_([NSStringPboardType], None)\n\
board.setData_forType_(content, NSStringPboardType)\n\
\" | /usr/bin/python"];
DeleteFile[{out <> ".txt", out <> ".rtf"}]]],
Method -> "Queued"]
SelectionMove[EvaluationNotebook[], Previous, Cell];
FrontEndExecute[FrontEndToken["GeneratePalette"]];
FrontEndExecute[FrontEndToken["Clear"]];
Now you can also install this permanently by going to Palettes > Install Palette and selecting a name for the palette.
copyAsUnicode function by itself? I'll get back to this later, but any additional info would help. Is the error message generated when you try to paste into some external application (which one)? I'm trying to understand if it's the button code or the original function that isn't working (it works for me).

Here's how to add a permanent menu item and keyboard shortcut for Silvia's solution. (This can be easily adapted to Jens' solution for Mac OS.)
Copy Silvia's first code block that starts with Needs["NETLink`"] to a file and save it as UniCodeCopy.m in one of the directories included in $Path.
Save the following to the file $UserBaseDirectory/Autoload/FrontEnd/init.m (create it if needed):
Needs["UniCodeCopy`"]
CopySelectionAsUnicode[] :=
Module[{selection, code},
FrontEndExecute[FrontEndToken["CopySpecial", "InputText"]];
selection = NotebookGet[ClipboardNotebook[]][[1, 1, 1]];
code = StringReplace[selection, {"\\\n" -> "",
"\n" ~~ space : " " ... :> StringJoin["\n", ConstantArray[space, 4]]}];
UniCodeCopy`WriteToClipboardUnicode[code];]
FrontEndExecute[
FrontEnd`AddMenuCommands["Copy",
{MenuItem["Copy as Unicode",
FrontEndExecute[CopySelectionAsUnicode[]],
(* Alt + U *)
MenuKey["u", Modifiers -> {"Command"}],
System`MenuEvaluator -> Automatic,
Method -> "Queued"]}]]
For key bindings, the possible modifiers are "Shift", "Control", "Command" (Alt) and "Option" (Alt).
(It took me a few hours to figure this out. I hope this proves useful for other struggling novices.)
$UserBaseDirectory/Autoload/FrontEnd/init.m should be created, because there is no such file on my Windows 8.1 computer? There is, however, the file $UserBaseDirectory/FrontEnd/init.m on my computer, but appending your code to the end of that file caused Mathematica 10.0.2.0 to crash during initialization. Thanks in advance for your assistance.

Here is a function that copies a Unicode string to the clipboard using JLink:
Needs["JLink`"];
InstallJava[];
LoadJavaClass["java.awt.Toolkit", AllowShortContext -> False];
uniclip[s_String] :=
JavaBlock[
javaawtToolkit`getDefaultToolkit[]@getSystemClipboard[]@setContents[#, #]& @
JavaNew["java.awt.datatransfer.StringSelection", s]
];
From Mathematica 12.3 onward, we can use ExternalFunction instead of JLink (thanks to Ben Izd for pointing this out):
uniclip = ExternalFunction["Java",
"static void uniclip(String string) {
var s = new java.awt.datatransfer.StringSelection(string);
java.awt.Toolkit.getDefaultToolkit().getSystemClipboard().setContents(s, s);
}"
];
Example usage:
expr = \[Alpha]\[Beta] + Mod[\[Delta]\[CapitalPsi], 2\[InvisibleTimes]\[Rho]^2];
uniclip @ ToString[expr, InputForm]
After evaluating these expressions, the clipboard contains αβ + Mod[δΨ, 2*ρ^2].
uniclip into another answer that adds menu items and shortcut keys, feel free.

uniclip is broken on Windows 10 in recently released M13.2. One of the error messages was "Java failed to load class sun.awt.windows.WClipboard."
– Silvia
Dec 22 '22 at 08:26
ExternalEvaluate which can be used as a workaround for the error. We can use this definition of uniclip which is exactly the same but in Java:
– Ben Izd
Dec 22 '22 at 17:00
uniclip = ExternalEvaluate["Java", "import java.awt.Toolkit; import java.awt.datatransfer.StringSelection; import java.awt.datatransfer.Clipboard; public static void copy(String string){ StringSelection selection = new StringSelection(string); Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard(); clipboard.setContents(selection, selection); } "]

ExternalEvaluate.

Here's a version that doesn't require a temporary file.
xclip)SetAttributes[copyUnicode, HoldAll];
copyUnicode[expr_] := With[{
stream = OpenWrite["!xclip -in -selection clipboard", CharacterEncoding -> "UTF-8"]
},
WriteString[stream, ToString[Unevaluated@expr, InputForm]];
Close@stream;
];
Example: executing the cell
Cell[BoxData[
RowBox[{"copyUnicode", "[",
RowBox[{
RowBox[{
RowBox[{
SuperscriptBox["x", "2"], "\[SmallCircle]",
RowBox[{"{",
RowBox[{
RowBox[{"\[LeftFloor]", "\[Alpha]", "\[RightFloor]"}], ",",
"\"\<\[LeftFloor]\[Alpha]\[RightFloor]\>\""}], "}"}]}],
"\[PlusMinus]",
RowBox[{
SqrtBox["5"], "\[CirclePlus]", "\[HappySmiley]"}]}],
"<=",
"\"\<\[Integral]\[PartialD]\[RightArrow]\[Union]\[Sum]\[Infinity]\
\[Element]\>\""}], "]"}]], "Input"]
gives x^2 ∘ {Floor[α], "⌊α⌋"} ± Sqrt[5] ⊕ ☺ <= "∫∂→⋃∑∞∈".
Not tested, but it should work if you use "!clip"instead of"!xclip -in -selection clipboard"`. You might have to change the encoding to UTF-16.
InputForm when not inside a string.ℝ, even when a standard code point exists, so the output will be wrong if the input contains such characters.
\[UpEquilibrium], get converted incorrectly or not at all, no matter what I try. So I don't think it's possible to get a perfect translation to Unicode in general.

Here's a method that's really no different from the standard ones except it's generalized for copying cells and, theoretically, for Windows and Unix.
We'll use RunProcess because this exists now, and tweak the ProcessEnvironment to make it work for Mac:
FrontEnd`unicodeCopy[s_String,
enc : _String | Automatic : Automatic,
lang : _String | Automatic : Automatic
] :=
With[{
encoding = Replace[enc, Automatic :> $CharacterEncoding],
language = Replace[lang, Automatic :> $Language]
},
If[#["ExitCode"] =!= 0,
FrontEnd`unicodeCopy::copyerr = "error in copy process:\n ``";
Message[FrontEnd`unicodeCopy::copyerr, #["StandardError"]];,
#["StandardOuput"];
] &@
RunProcess[
Switch[$OperatingSystem,
"Windows",
"clip",
"MacOSX",
"pbcopy",
"Unix",
{"xsel", "-b"}
],
All,
ExportString[s,
"String",
CharacterEncoding -> encoding
],
ProcessEnvironment -> <|
"LANG" ->
Replace[ToLowerCase@language,
"english" -> "en_US"
] <> "." <>
Replace[encoding, {
"UTF8" -> "UTF-8",
"Unicode" -> "UTF-16"
}],
"PATH" -> Environment["PATH"]
|>
]
];
(I'm using FrontEnd` for when I dump to "MenuSetup.tr", just so it looks consistent)
Now we'll define a bunch of junk to generalize to make it work across an NB:
$unicodeTR =
FrontEnd`FindFileOnPath["UnicodeCharacters.tr",
"PrivatePathsTextResources"] // FrontEndExecute;
$unicodeReplacements = #[[2]] ->
ToExpression[
"\"" <> StringReplace[#[[1]], {"x" -> ":",
StartOfString ~~ "0" -> "\\"}] <> "\""] & /@
Rest[
StringSplit@StringSplit[Import[$unicodeTR, "String"], "\n"]
];
FrontEnd`UnicodeCopy[c : {__Cell}] :=
Replace[
MathLink`CallFrontEnd[
ExportPacket[Cell[CellGroupData[c]], "InputText"]
], {
{s_String, __} :>
FrontEnd`unicodeCopy@
StringReplace[s,$unicodeReplacements]
}];
FrontEnd`UnicodeCopy[c_Cell] :=
Replace[
MathLink`CallFrontEnd[
ExportPacket[c, "InputText"]
], {
{s_String, __} :>
FrontEnd`unicodeCopy@
StringReplace[s,$unicodeReplacements]
}];
FrontEnd`UnicodeCopy[b_BoxData | _TextData] :=
FrontEnd`UnicodeCopy@Cell[b];
FrontEnd`UnicodeCopy[b_RowBox] :=
FrontEnd`UnicodeCopy@Cell[BoxData@b];
FrontEnd`UnicodeCopy[
nb : _NotebookObject | _FrontEnd`NotebookObject | \
_FrontEnd`SelectedNotebook | _FrontEnd`InputNotebook | \
_FrontEnd`ButtonNotebook | _FrontEnd`EvaluationNotebook | \
_FrontEnd`MessagesNotebook | _FrontEnd`HelpBrowserNotebook | \
_FrontEnd`ClipboardNotebook
] :=
FrontEnd`UnicodeCopy[Evaluate@NotebookRead@nb];
FrontEnd`UnicodeCopy[
nb : _InputNotebook | _EvaluationNotebook | _ClipboardNotebook | \
_ButtonNotebook | _MessagesNotebook | _HelpBrowserNotebook] :=
FrontEnd`UnicodeCopy@Evaluate@nb;
FrontEnd`UnicodeCopy[Optional[Automatic, Automatic]] :=
FrontEnd`UnicodeCopy@InputNotebook[];
FrontEnd`UnicodeCopy[s_String] :=
FrontEnd`unicodeCopy[s];
FrontEnd`UnicodeCopy[e_] :=
FrontEnd`UnicodeCopy[Evaluate@ToString[Unevaluated[e], InputForm]];
FrontEnd`UnicodeCopy~SetAttributes~HoldFirst
Then I'll add this to my MenuSetup using the framework I wrote up here and whose up-to-date implementation lives here
FEMenuSetupAdd[
{"Edit", "Copy As", 5},
"Unicode" -> KernelExecute[ToExpression["FrontEnd`UnicodeCopy[]"]],
MenuEvaluator -> Automatic,
System`MenuKey["C", System`Modifiers -> {"Control"}]
]
This now lives under the "Copy As" menu:
And it can be used by function:
FrontEnd`UnicodeCopy["asdasd\[Alpha]\[Beta]\[Gamma]"]
asdasdαβγ
FrontEnd`UnicodeCopy[Cell["asdasd\[Alpha]\[Beta]\[Gamma]"]]
asdasdαβγ
Or by Control-C:
FrontEnd`UnicodeCopy[Cell["asdasdαβγ"]]
(fixed, now, by doing a more selective replacement from UnicodeCharacters.tr)
One issue here is that I was a bit over zealous with some replacements when copying from cells and boxes (has to do with what comes out of the ExportPacket):
(Command-C): "asdasd\\[Alpha]\\[Beta]\\[Gamma]"
(Control-C): "asdasd\α\β\γ"
And just to include the original example:
\[Alpha]\[Beta] +
Mod[\[Delta]\[CapitalPsi], 2\[InvisibleTimes]\[Rho]^2]
becomes:
αβ +
Mod[δΨ, 2ρ^2]
(note how, unfortunately, the added spacing from the cell copy is preserved)
Edit: Updated code
As a generalization to the excellent answer by ens, Silvia's solution also can be added as a palette to the menu as follows. First, create and save the UniCodeCopy.m package, as described by ens. Then create as a separate notebook, perhaps named Unicode Copy Source.nb,
NotebookPut[
Notebook[{Cell[BoxData[ButtonBox["\"UniCode Copy\"", Appearance -> Automatic,
ButtonFunction :> Module[{codestr},
AppendTo[$Path, FileNameJoin[{$UserDocumentsDirectory,
"Mathematica/MyPackages"}]];
Needs["UniCodeCopy`"];
FrontEndExecute[FrontEndToken["CopySpecial", "InputText"]];
codestr = (StringReplace[#1, {"\\\n" -> "", "\n" ~~ space : " " ... :>
StringJoin["\n", ConstantArray[space, 4]]}] & )
[NotebookGet[ClipboardNotebook[]][[1, 1, 1]]];
UniCodeCopy`WriteToClipboardUnicode[codestr]],
Evaluator -> Automatic, ImageSize -> 200, Method -> "Queued"]],
NotebookDefault]}, WindowSize -> {Fit, Fit},
WindowMargins -> {{Automatic, 522}, {Automatic, 41}},
WindowFrame -> "Palette", WindowElements -> {},
StyleDefinitions -> "Palette.nb"], WindowTitle -> "UniCodeCopy"];
NotebookSave[%, FileNameJoin[{$UserDocumentsDirectory,
"Mathematica/MyPackages/UniCodeCopy.nb"}]]
Note that the third and fourth lines of code add the location of UniCodeCopy.m (in this case, my Mathematica/MyPackages directory) to $Path, if the location is not already there. (If it is there, these two lines of code can be omitted.) Executing Unicode Copy Source.nb creates the small palette, UnicodeCopy.nb, saved in Mathematica/MyPackages. Finally, use the Install Palette ... command in the Palette menu to register UnicodeCopy.nb as a palette. After Mathematica is restarted, it will display UnicodeCopy in the Palette menu.
Under windows with Nircmd available, one can add the code below (a modification of https://mathematica.meta.stackexchange.com/a/155/9754) to an initialization cell of
$UserBaseDirectory <> "\\Autoload\\FrontEnd\\init.m" to get Alt Gr+p as a shortcut for copying as unicode and having 4 spaces added at the beginning of each line.

But I would say that a more modular design would be to letcopyUnicodeonly acceptStringin the first place, and leave it to the calling function to provide the string.
