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

If not, how can I tell \unit that C is missing and that I want \unit{celsius} to use D?

Should we care about? It's no problem to make an option to always use the split version.

Should we care about? I think for ConTeXt purposes we should just ignore the composed form, it is there only for compatibility with some legacy CJK encodings and their use is almost discouraged. If user enters those code points directly, then he on his own, so nothing to be done here either. In short, this is just some of the compatibility nonsense crippling Unicode, we are better off pretending they do not exist Regards, Khaled ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 10+ messages in thread
