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?
With dejavu, A, B, and D all work, but C is missing a symbol.
A 100℃
B 100°C
C $100℃$
D $100°C$
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?
Hans can add a check for math mode for the symbol:

\unprotect

\unexpanded\def\checkedtextcelsius
  {\ifmmode
     \phys_units_text_celsius
   \else\iffontchar\font"2103\relax
     ℃\else\phys_units_text_celsius
   \fi\fi}

\unexpanded\def\checkedtextfahrenheit
  {\ifmmode
     \phys_units_text_fahrenheit
   \else\iffontchar\font"2109\relax
     ℉\else\phys_units_text_fahrenheit
   \fi\fi}

\protect

\setupbodyfont[dejavu]

\starttext
  Temperature : \unit{100 celsius} works.\par
  Temperature : \m{\unit{100 celsius}} doesn't work.
\stoptext
