It turns out that the unicode-math package I was using was an old one (0.7e) and the new version (0.7f) does not have the problem... Also, in case anyone gets into trouble with the package updating and both TeXworks and the package updater cannot run (they complain of missing DLLs), I solved it by copying the old DLLs (I'm on Windows so I could retrieve them ...

First of all, you have to check if your desired commands are already defind: % arara: xelatex \documentclass{article} \usepackage{unicode-math} \show\feq \show\nfeq \begin{document} foo \end{document} The .log shows: > \feq=undefined. l.12 \show\feq > \nfeq=undefined. l.13 \show\nfeq So there should be no problem in using those. If they ...

In the next version of unicode-math there'll be an interface for this: \setmathfontface\mathfoo{texgyrechorus-mediumitalic.otf} \setoperatorfont\mathfoo Please speak up if you think there might be a better way to do this :)

The question is somewhat general, but refers to the specific problem of periods, which have a special meaning for TeX delimiters. (Choosing other punctuation from other fonts works fine, right?) My understanding is that they should always have delcode of zero; unicode-math has a line of code to ensure this, and due to a broader bug in how range is ...

Ah, thanks very much for spotting this! The reason this occurs is two-fold. Firstly, when loading a maths font, unicode-math queries it to establish the sizes it should define for script and scriptscript sizes. After doing this, it needs to re-load the font with these new sizes, and that wasn't happening. (I don't know if this was actually a problem in ...

The problem has a long history. It was brought up in 2011, as far as I know, with a message to the TeX Live mailing list; the thread went on also in the LuaTeX list. The problem is that LuaTeX doesn't add the italic correction in math mode after characters having category code 11. Indeed, in TeX Live 2011, the output from your code would be the same as you ...
