I've got a problem, that I can't fix. As soon as I try to use Cambria Math as font for \mathscr and \mathbfscr I get a

"missing \endcsname inserted"

as error. I'm new to LuaLaTeX so I simply copied this line from a pdf document that I've found. Everything works fine when I use Cambria Math directly with \setmathfont instead of xits. So the font itself seems to be installed correctly.

\setmathfont{Cambria Math}
\setmathfont[range={\mathscr,\mathbfscr}]{Cambria Math}

    Hello world!

Maybe someone can help me with that.

  • Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. Thanks for including an example with your question. Could you make it a minimum working example and take out any lines that aren't necessary to reproduce the problem? – darthbith Jul 1 '14 at 12:24
  • If I keep only the document class (without options), the amsmath package, the unicode-math package, and the line setting the math font to Cambria Math (I don't have the xits fonts, so I had to comment out those lines) I cannot reproduce this error. I did note some similar error with the polyglossia package in my brief tests... – darthbith Jul 1 '14 at 12:27

    According to the last commit, the fixltx2e package is no longer loaded by fontspec. If I put \RequirePackage{fixltx2e}[2006/03/24] before \documentclass, the MWE compiles successfully (NB the commit message of that commit notes that it is recommended to load fixltx2e before \documentclass). – darthbith Jul 1 '14 at 15:12

    This post appears to be off-topic because it is about an issue in unicode-math that has been fixed: github.com/wspr/fontspec/issues/178 github.com/wspr/unicode-math/commit/… (@Sebastian Don't worry, this is just for house-keeping. Good question!) – darthbith Jul 2 '14 at 14:47
