@moewe tod: Is it U+2016 or U+2061? The tex error should indicate a line number. Do you have anything strange on that line? Some symbol you copy and pasted? – Teepeemm Apr 11 '19 at 15:59

@Teepeemm it is U+2061 – tod Apr 11 '19 at 16:01

U+2061 is FUNCTION APPLICATION that is an invisible zero width character intended to distinguish concatenation meaning function application from concatenation meaning multiplication,. You should be able to simply delete it. – David Carlisle Apr 11 '19 at 16:06

@DavidCarlisle How can i delete it? I am using Winedt – tod Apr 11 '19 at 16:16

just delete the line and retype that line for example, the full error message from the log shows you where the character is. – David Carlisle Apr 11 '19 at 16:16

Yes, it does show me the line number... deleted the line several times and retyped. unfortunately, that's not working. – tod Apr 11 '19 at 16:18

If deleting it is hard then declare it to do nothing add this to the document preamble
\DeclareUnicodeCharacter{2061}{}

@StevenB.Segletes can you suggest a better tex definition for a character defined to have no effect on visual output? :-) – David Carlisle Apr 11 '19 at 16:11

Thanks @DavidCarlisle when I use it, it gives the same error even on my system... I have tried it even before... Maybe let me check it on springer website after using this line. – tod Apr 11 '19 at 16:12

@tod no, it can't give a character not defined error after you define the character. Please post a small example document that shows the problem. – David Carlisle Apr 11 '19 at 16:13

\DeclareUnicodeCharacter{2061}{}with this it gives error: Undefined control sequence\DeclareUnicodeCharacter{2061}{} – tod Apr 11 '19 at 16:23 -

@tod that is a different error :-) and means you have an old latex, add
\usepackage[utf8]{inputenc}before the definition. – David Carlisle Apr 11 '19 at 16:29 -
1Would it be possible to do something like
\DeclareUnicodeCharacter{2061}{X}, so that the output would show where the offending character is hiding? – Teepeemm Apr 11 '19 at 17:45 -
1@Teepeemm , yeah this works too. You could place any character in the brackets. – Doesbaddel Apr 11 '19 at 17:52

If there is a part of the text where you think invisible U2061 is hidden then you can copy and paste it to Microsoft Word using "Keep Text Only" option and the hidden symbols will be visible. You can delete them and then copy paste the edited text back into TeX.
