[NTG-context] LuaTeX and Unicode Math

While trying to convert some stuff from HTML to PDF (using LuaTeX) I
have noticed some minor problems: unicode math characters work OK in
text mode (under assumption that the font has them), but not in math
mode. In pdfTeX they work OK in both cases. (That behaviour is
expected, but not necessary desired.)

Is there any cure to it?

% in LM, most characters are not present in otf fonts, so with LM this
wouldn't work at all. Iwona is slightly better in that respect.

\def\testA{(φ)} % 03c6
\def\testB{(・)} % 00b7
\def\testC{(≤)} % 2264


I could/should solve the problem with better handling of xml entities
or with fallbacks (if φ is not present in font, use \phi etc.), but I
don't know how to do either of them.

I would normally say something like
to solve the problem, but that doesn't work when doing XML conversion.
