Hi Hans,
I simply put the unicode character there and everything works pretty well.
I was using only 5 Chinese characters in a document: 中國科學院, which means Chinese
Academy of Sciences. Looked up their unicode number:
for c in u'中國科學院': print(ord(c))
20013
22283
31185
23416
38498
and draw every glyph carefully in a metapost file "cas-chars.mp":
beginglyph(20013,1000,1000,0);
% a lot of fillings and drawingsendglyph;
then call them in a test file:
\definemetafont[cas-logo][cas-chars.mp]
\startTEXpage
\definefont[cas][cas@cas-logo]
\cas 中國科學院\stopTEXpage
If I remove the beginglyph(38498,1000,1000,0) part in the mp file and “\cas
中國科學” will generate the correct output. or if I change
beginglyph(38498,1000,1000,0) to beginglyph(32767,1000,1000,0) and “\cas
中國科學\char"7FFF” also gives the right output.
I'm looking forward to “some” module :-)

How do you use these symbols in a document? Do you call them up by
number somehow? Using some glyph interface doesn't make much sense I
think, as the font stuff comes from mf which is 8 bit. So, these
character numbers (and simensions) are not really saying much, other
than that they're properties of a figure.
(In context lmtx there will likely be some module for mp fonts. We can
already do a lot but there is some more potential.)
