Hi, After updating unicode-math to the most recent version I'm experiencing an unwanted behavior which seems to be related with the keys "script-features" and "sscript-features". The log resulting from the compilation of the following code: **** \documentclass{article} \usepackage{fontspec} \usepackage[math-style=TeX]{unicode-math} \setmathfont[]{Asana Math} \begin{document} $\alpha_n$ and $\alpha_{n_k}$ \end{document} **** contains several error messages as bellow: ***** ./teste.tex:5: Undefined control sequence. <argument> \...@update@ff {+ssty=0} l.5 \setmathfont{Asana Math} ? ./teste.tex:5: LaTeX Error: Missing \begin{document}. See the LaTeX manual or LaTeX Companion for explanation. Type H <return> for immediate help. ... l.5 \setmathfont{Asana Math} ? ./teste.tex:5: Undefined control sequence. <argument> \...@update@ff {+ssty=1} l.5 \setmathfont{Asana Math} ? ./teste.tex:5: Missing number, treated as zero. <to be read again> \g_um_up_misc_usv l.5 \setmathfont{Asana Math} ? ./teste.tex:5: Missing number, treated as zero. <to be read again> \g_um_it_misc_usv l.5 \setmathfont{Asana Math} ? ./teste.tex:5: Missing number, treated as zero. <to be read again> \g_um_bb_misc_usv l.5 \setmathfont{Asana Math} ? ./teste.tex:5: Missing number, treated as zero. <to be read again> ./teste.tex:5: Missing number, treated as zero. <to be read again> \g_um_bfsfit_misc_usv l.5 \setmathfont{Asana Math} ? ? ****** resulting in the output shown in the attachment (output.png).  Misusing the \setmathfont command, substituting "\setmathfont[script-features=,sscript-features=]{Asana Math}" for "\setmathfont{Asana Math}" results on a similar log file except for the lines of the kind Undefined control sequence. <argument> \...@update@ff {+ssty=0} that no longer appear. This has the only advantage (if the term applies here) that the text "+ssty=0+ssty=1" no longer appears in the pdf file and I can compile my text as long as I do it in nonstop mode. Any help will be welcome. Thanks! António Fernandes |
