Beats me. I don't know what you mean by grapheme. Or glyph. :-) The web has a wide variety of definitions, most of them centered on some association with a spoken language (the grapheme/phoneme association). While that certainly covers what I think you mean - letters, ideographs, diacritical combinations, etc. - and I'm fairly certain that extends to other written representations of language - punctuation, white space, numerics - I don't know if it extends to things that aren't. The Arabic tatweel (0x0640), for instance, is pure a typesetting construct. Then you've got non-language things like math operators, arrows, and "dingbats". And *then* you've got several ranges of "Presentation Forms", which Unicode explicitly references as glyphs. For instance, see 0xFB50 - 0xFDFF, Arabic Presentation Forms-A. Perhaps fred *is* better. -- Bryan C. Warnock bwarnock@(gtemail.net|raba.com)
