One other thought: since TAB and SPC are single-byte characters,
whereas the other "whitespace" characters are not, supporting the
non-ASCII whitespace will be associated with some performance hit in
the display engine, because it requires a char-table look up and
fetching multibyte characters. So perhaps we should allow the
word-wrap-chars char-table to be nil (and make that the default), and
in that case support only TAB and SPC as word-wrap characters. This
would let the default configuration work as fast is it does now,
imposing the performance penalty only on those who want to support
more whitespace characters.
WDYT?
