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 :-) ------------------------------------------------------------------ From:Hans Hagen Send Time:2019 Jul. 5 (Fri.) 17:03 To:陈之初 ; mailing list for ConTeXt users Subject:Re: [NTG-context] I (metapost) can't handle numbers bigger than 32767.99998 On 7/5/2019 8:32 AM, Zhichu wrote: > 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.)

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. > > > > > > > ___________________________________________________________________________________ > 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://context.aanhet.net > archive : https://bitbucket.org/phg/context-mirror/commits/ > wiki : http://contextgarden.net > ___________________________________________________________________________________ > -- ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl ----------------------------------------------------------------- ___________________________________________________________________________________ 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://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________
