OK. Looking back, there was also some mention of changing chr's
argument to bigint, but I'd counsel against doing that. We should not
need it since we only support 4-byte UTF8, hence code points only up to
21 bits (and indeed even 6-byte UTF8 can only have 31-bit code points,
no?).
If Tatsuo can find official code-point mappings for any other MB
encodings, +1 on supporting those too.
