setmathface mathbf not working properly

ghost commented 5 years ago

Description

Define \mathbf with \setmathface fails to give anything, see the mwe and the output mwe.pdf. The example below used to work great one year ago.

\usepackage[math-style=ISO,bold-style=ISO]{unicode-math}

\setmathfontface\mathbf{MinionMath-Bold}[ Extension = .otf, ]

\setmathfont[%
    Extension = .otf,%
    Scale = 1,%
    Script = Math,%
]{MinionMath-Regular}

\begin{document}

\( \mu \mathbf{\mu}\)

\end{document}

Can someone please find out what goes wrong here? Perhaps I made a mistake, instead of finding a bug of unicode-math. Any input is appreciated.

~~Simply because there's no such \setmathfontface command…~~

To use bold font, you should try the "math version" feature. I think it has been clearly described in the unicode-math documentation.

Please read section 4.4 in the unicode-math.pdf.

If you want bold math symbols use \symbf. \mathbf is for loading a bold text font in a mathematical context.
