Thanks for taking the time to report an issue! Any apologies that I take longer, sometimes way longer, than I should to address them.
There are two important key points for submitting an issue:
- When submitting an issue, please include a complete minimal example.
- When loading maths fonts, please do so by filename only.
- If you are using a proprietary/unusual font, please try a maths font in TeX Live to see if it exhibits the same behaviour; it's obviously much harder for me to test with fonts I don't yet have or can't access.
For example, this is a good minimal example:
\documentclass{article}
\usepackage{unicode-math}
\setmathfont{texgyrepagella-math.otf}
\begin{document}
\[
x^2 + y^2 = z^2
\]
\end{document}
This is an example of a bad example:
\usepackage{unicode-math}
\setmathfont{TeX Gyre Pagella Math}
% later:
\[
x^2 + y^2 = z^2
\]
There are two main branches in this repository: master and working.
Development happens on the working branch; once a release is sent to CTAN,
the master branch is rebased to bring it up to date.
The working branch should be considered only semi-public; it may have broken
code and/or use force-pushing to rewrite history on occasions.
If you wish to make a contribution, please start from the master branch.
If you are changing documentation only (i.e., no code changes), you can add
[ci skip] to the commit message and the test suite won't be run to check that
the changes haven't broken anything.
Copyright statements in most package files are updated en masse by the bash script
update-copyright.sh using the file COPYRIGHT as a template.
(The updating script has been tested on macOS only.)
Contributors are listed in the copyright statement if they have more than one entry in the following list:
git log --all --date=short --format='%cN %ad' | sed 's/\(.*[0-9]*\)-[0-9]*-[0-9]*/\1/' | sort -u
Contributors are added to the COPYRIGHT file manually. If your name doesn't appear in that list, you might need to check your Git setup.
