| 103 The format of a fontname (as returned by fontconfig) is not well-documented, | |
| 104 But the character repertoire is represented in an ASCII-compatible way. See | |
| 105 fccharset.c (FcCharSetUnparse). So we can use UTF-8 for long names. | |
| 106 | |
| 107 Currently we have a hack where different versions of the unparsed name are | |
| 108 used in different contexts fairly arbitrarily. I don't think this is close | |
| 109 to coherency; even without the charset and lang properties fontconfig names | |
| 110 are too unwieldy to use. We need to rethink the approach here. I think | |
| 111 probably Lisp_Font_Instance.name should contain the font name as specified | |
| 112 to Lisp (almost surely much shorter than shortname, even, and most likely | |
| 113 wildcarded), while Lisp_Font_Instance.truename should contain the longname. | |
| 114 For now, I'm going to #ifdef the return values defaulting to short. -- sjt | |
