Can this still happen?  When?
When INDEX_TO_CODE_POINT returns a code point greater than
most-positive-fixnum, which can happen (in theory, at least) on 32-bit

Can it, really?

I don't know of any way it could happen. So what you're saying is that we should install something like the attached patch?

Also, how about glyph-ids returned by font-variation-glyphs? Can they exceed fixnum range? If not, font-variation-glyphs could see a similar speedup.
