The bug here is likely that setting a character in a unibyte string to a
value between 160 and 255 does not result in an automatic conversion to
multibyte.  That was correct in 22.3, since values in that range were
raw binary bytes outside of any character set, but in 23.1 they correspond
to valid Latin-1 codepoints.
