Bug#852521: [tex-live] unicode-math now unable to process $\widetilde{\mathbf{a}}$

[Norbert Preining <preining@logic.at>]

Dear James,

I guess you haven't seen the answer on the TeX Live mailing list,
so I add it here.

It seems that this has been the case before, too, and is well known:


*** answer from Ulrike Fischer *****

The problem is that \mathbf doesn't use a font with math table and
accent commands don't like this. You can find quite a number of
questions about this on tex.sx. E.g.
http://tex.stackexchange.com/questions/214570/try-to-use-ams-blackboard-bold-font-together-with-texgyrepagella

The correct input would be \symbf. Or you must hide the \mathbf in a
box:

\documentclass{article}
        \usepackage{unicode-math}

        \begin{document}
          $\widetilde{\symbf{a}} \widetilde{\mbox{$\mathbf{a}$}}$
        \end{document}

(\widetilde{\text{$\mathbf{a}$}} with amsmath work too)

********************

Can you confirm that this *has* worked before, say in the last
half year or so?

If not, I will probably close this bug report as usage error
or upupstream problem.

All the best and hope that helps

Norbert
