You cannot always match all non-@acronym{ASCII} characters with the regular
expression @code{"[\200-\377]"}. This works when searching a unibyte
buffer or string (@pxref{Text Representations}), but not in a multibyte
buffer or string, because many non-@acronym{ASCII} characters have codes
above octal 0377. However, the regular expression @code{"[^\000-\177]"}
does match all non-@acronym{ASCII} characters (see below regarding @samp{^}),
in both multibyte and unibyte representations, because only the
@acronym{ASCII} characters are excluded.
