I'm glad to hear that more people are decimalising: it certainly makes a
lot of things easier. In the meantime, however, it is possible to use
contextual glyph substitution in OpenType (and I presume in Apple's AAT
also) to build vulgar fractions of size from numerator and denominator
glyphs. I spent some of last week figuring out the best way to do this.
If anyone out there is building OpenType font tables using Microsoft's VOLT
tool, you might want to download my fraction implementation from
http://www.tiro.com/transfer/VOLT_Fractions_Feature_(Tiro).EXE
This is a self-extracting zip file that includes VOLT glyph group and
lookup definition files and documentation.
