Miktex users which updated to the newest xetex engine (version 3.1415926-2.4-0.9998 (MiKTeX 2.9)) report problems with subscripts in math.
http://tex.stackexchange.com/questions/121769/miktex-amsfont-problem-scriptfont-is-undefined http://tex.stackexchange.com/questions/121276/updating-miktex-again-errors \documentclass{article} \usepackage{unicode-math} \begin{document} $a_{b1}$ \end{document} gives the error ! \textfont 197 is undefined (character .5). l.6 $a_{b1}$ If one continues the output looks ok. The same document compiled with TL13 gives no error but there is a suspicious missing character message in the log which imho could be related: Missing character: There is no Dž in font [latinmodern-math.otf]/ICU:script=math ;language=DFLT;! On a miktex without the new xelatex engine but the same unicode-math version there is no problem. -- Ulrike Fischer http://www.troubleshooting-tex.de/ -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
