The big problem was not handling \mathit properly.

It has been possible for a long time to select a text font for a math alp=
habet in unicode-math, but this feature was probably not documented very =
well.
If you try to select a particular unicode range such as \mathbfup and a f=
ont simply doesn=92t have it (well, it only checks =93A=94 I think), the =
remapping doesn=92t occur and you get the ascii-range glyphs:

\documentclass{article}
\usepackage{fontspec}
\usepackage{unicode-math}
\setmainfont{texgyretermes-regular.otf}
\setmathfont[range=3D\mathbfup]{texgyreheros-bold.otf}
\begin{document}
text \textbf{bold}
\[ m+a+t+h \quad \mathbf{b+o+l+d} \]
\end{document}

BUT this doesn=92t work properly with \mathit, because unicode-math hasn=92=
t distinguished =93math alphabetic symbols=94 from =93math text font=94.

Cheers,
Will
