I just updated my TeX live installation (tlmgr update --all) and now I get some wrong symbols in math mode if I use XeLaTeX or LuaTeX. This MWE for example

$. + , - / $

produces the following output:

wrong symbols

I suppose it is a bug in the new Latex2e version from 2016/02/01. Any ideas how to fix this?


Adding \usepackage{fontspec} produces a different output. But it is still not perfect.

wrong symbols 2

  • I believe a fix is on its way to TeX Live.

    \usepackage{fontspec} (which most xetex/luatex documents need anyway) will partially fix it, but the real fix to the format should appear hopefully in the next tl update. Feb 3, 2016 at 21:12
  • @DavidCarlisle Actually adding fontspec does not fix everything for me. I edited my post.

    No it doesn't if you can not wait for the next update get github.com/latex3/unicode-data/blob/master/… and then use fmtutil-sys to rebuild the formats, sorry about the inconvenience. Feb 3, 2016 at 21:23
