[NTG-context] Missing °C symbol in math mode with dejavu font
Hi all,
The °C symbol is missing in math mode with the dejavu font. I thought that
this should be handled by using the '°' + 'C' symbols instead but it is not
the case.
Is that a bug?
What can I do to get the °C symbol with this font?
%% MWE
\setupbodyfont[dejavu]
\starttext
Temperature : \unit{100 celsius} works.\par
Temperature : \m{\unit{100 celsius}} doesn't work.
\stoptext

The question is: do \unit is supposed to handle this case and automatically
switch from C to D if C is missing.
If not, how can I tell \unit that C is missing and that I want \unit{celsius}
to use D?
Thanks

Hans can add a check for math mode for the symbol:
\unprotect
\unexpanded\def\checkedtextcelsius

My suggestion is to just use \phys_units_text_* always, since the
decomposed, two characters is the preferred form for those two units.
