Is there an alternative for \XeTeXglyph that works in math mode? Or is there a way \XeTeXglyph itself can work in math mode?

I want to access a specific glyph as a math symbol (UF091F specifically) in Minion Math using \XeTeXglyph but each time I try an error comes up saying ! You can't use \XeTeXglyph in math mode.

Using \symbol{######} works fine in LuaLaTeX but I think because the glyph I want is a 6 digit number, in XeTeX it outputs ! Bad character code (######) (where ###### is the symbol number as found using this method. Hence why I'm trying to use \XeTeXglyph, unless there actually is a way of using \symbol for that glyph without that error?

I use a glyph called by index with a font I have, in this case XITS Math.

\documentclass{article}
\usepackage{amsmath}
\usepackage{unicode-math}
\setmainfont{TeX Gyre Pagella}
\setmathfont{Asana Math}

\newfontfamily{\test}{XITS Math}

\begin{document}

{\test\XeTeXglyph4491}

$A\mathrel{\text{\test\XeTeXglyph4491}}B$

$A\mathbin{\text{\test\XeTeXglyph4491}}B$

$A\mathpunct{\text{\test\XeTeXglyph4491}}B$

\end{document}

Of course you'll want to make a macro.

On the other hand, either \symbol{985375} or \symbol{"F091F} should work, provided you hide them inside \text. I happen to have a font that has a glyph in that position:

\documentclass{article}
\usepackage{amsmath}
\usepackage{unicode-math}
\setmainfont{TeX Gyre Pagella}
\setmathfont{Asana Math}

\newfontfamily{\chn}{HanaMinPlus}

\begin{document}

{\chn\symbol{"F091F}}---{\chn\symbol{985375}}

$A\mathrel{\text{\chn\symbol{"F091F}}}B$

\end{document}

  • Thanks, that is the answer to my question technically... Problem is, seems like my glyph table from here doesn't link to the right glyph (it says 333 but when I put that in my doc it outputs the wrong symbol!). So let's say I want to stick to \symbol; when I put it in \text{\symbol{985375}} it outputs the symbol ☒ (guess that's an error; its supposed to be a lambda bar), and when I remove the \text it shows nothing except error message Bad character code (985375) :( – airatin Jan 10 '15 at 19:26
  • @airatin -- two forms of "lambda bar" should be in the xits/stix fonts: \lambdabar with a horizontal stroke and \lambdaslash with a slanted stroke. (i haven't checked the font, but since i was responsible for the names, that is what i found in my authoritative reference table. \lambdaslash should be at U+019B but \lambdabar is in the private use area, so there's no telling what conflicts there might be with other font definitions.) – barbara beeton Jan 10 '15 at 19:42
  • @barbarabeeton Thank you, however I do want to use Minion Math for the lambda bar symbol since it already is provided in it; I'm trying to avoid using other fonts unless absolutely necessary. – airatin Jan 10 '15 at 19:46
  • @airatin -- according to the unicode manual (5.0), "the entire plane 15, with the exception of the noncharacters U+FFFFE and U+FFFFF, is defined to be the supplementary private use area a." access to the private use area, in my (limited-mainly-to-theory) experience can be a touchy matter. if there is any documentation on this with respect to minion math, it would be a good idea to read it carefully. – barbara beeton Jan 10 '15 at 19:57
  • @barbarabeeton Using LuaLaTeX I get the correct output with that same symbol number, even though it is Private Use. It would be nice if XeLaTeX would allow the same :( also Typoma (creator of Minion Math) has nothing on their website for LuaTeX/XeTeX, so I could email the owner and see if he has any solutions. But still this same syntax should be allowed in XeTeX the way it is in LuaTeX :( – airatin Jan 10 '15 at 20:22
  • @airatin -- your observation regarding the syntax in xetex sounds good to me. you might look at the archives of the xetex mailing list to see if someone has already asked it, and, if not, send the inquiry yourself, to xetex@tug.org. – barbara beeton Jan 10 '15 at 20:30
