Perhaps so. There are probably several ways to index a collection of
fonts. FontForge is a tool I know well, so it's what I've used, and I've
got to say it's worked out pretty well, though Chris has obviously run
into a problem (which I can't reproduce) indexing a very large font on a
rather old (PIII) system.
It took me a few hours to write 334 lines of Python code that will
reliably tell you what fonts on your system contain a particular glyph.
I'm just an English professor, not a programmer: many people could do
this better, and perhaps someone ought to do it.
