Aha!  Thanks.  This deserves a comment in the code.

According to Wikipedia, GB-10830 has a max of ~1.5M codepoints (of the
4 bytes, the first and third are >128 and the second and fourth span
[30..39]), so we could fit them all into our fixnums just fine, but we'd
need to change the way we turn the 4byte sequence into a codepoint in
order to do that (I doubt the benefit would be worth the trouble).
