Very true unfortunately, but politics and font encodings are the art of the possible... There are two fonts which contain non-extensible math symbols: currently these are cmsy and cmmi, and it's pretty arbitrary which glyph is in which font. I'm not suggesting the Humanist/Geometric divide is a platonic division of glyphs, but a useful hack to make life slightly easier for font designers: a geometric CM symbol font should be adaptable for use with other fonts. >I don't understand why we want to put any non-mathematical characters >into the math fonts. Neither do I, but we have to find somewhere to put glyphs such as \dagger, \P, etc. Either we put them in a separate font, containing 71 glyphs (29 greek + 23 Greek + 10 alt. numerals + 3 music + 8 from cmsy) or we cram them into the math fonts (the Greek and numerals need to be in math anyway). I'm a bit worried about the amount of space math encoded character fonts would take up, without every text font having an extension font. >There aren't nearly enough positions in a 256-character encoding to >specify even all the useful math characters. Why even consider adding >the bullet and dagger and so forth? I agree totally---but these characters aren't in the Cork encoding, and we need to find homes for them. Either they should be in the math fonts (the current messy solution) or in a separate encoding (eating up even more font memory). Alan.
