input: accept Unicode codes for non-characters as valid, since they are

That is, accept U+FDD0 to U+FDEF, and accept U+xxFFFE and U+xxFFFF
for xx from 00 to 10 hex, being the 66 reserved "non-characters".

It may not be wise of the user to input these "things" (by typing
their code after M-V), but the codes are valid Unicode code points
and should not be rejected.

See https://www.unicode.org/faq/private_use.html#nonchar8 et al.

This fixes https://savannah.gnu.org/bugs/?60263.

Bug existed since before version 2.0.0.
