Hi everyone,
I was using metapost to generate some symbols, as in
"tex/texmf-context/metapost/context/fonts/mpiv/demo-symbols.tex"
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.)

Occasionally, I want to customize a glyph whose charcode is a little large, say the character "
院":
========================================
~~~IPython
In [1]: for c in u'院': print(ord(c))
38498
========================================
so I wrote:
========================================
beginglyph(38498,2,4,0) ; % high voltage
interim ahlength := 1 ;
drawarrow (1,4) -- (0,2) -- (2,3) -- (1,0) withcolor darkred ;
endglyph ;
========================================
and I got:
========================================
! Enormous number has been reduced.
l.60 beginzhglyph(38498
);
I can't handle numbers bigger than 32767.99998;
so I've changed your constant to that maximum amount.
========================================
So charcode is a 15-bit integer?
Currently, I use `beginglyph(32767,2,4,0) ;` and call it with \char"7FFF. Not
an elegant way I think.
Is there a fix? I checked the metapost manual and found that charcode is only
used to set the filename to something like %{jobname}.%{charcode} I can't see
why there's a limit for charcode.
