I missed this the first time around: All Unicode characters whose
lower 16-bits are FFFE or FFFF are non-characters, so you can re-write
that to:
/* U+xxFFFE and U+xxFFFF are guaranteed non-characters. */
if ((codepoint & 0xfffe) == 0xfffe)
return bad_offset;
Also, the range U+FDD0--U+FDEF are also non-characters, if you wish to
be really pedantic.
