Yet . matches. I think it's a documentation bug: [:unibyte:] matches only ASCII characters. IOW, it tests "unibyteness" in the internal representation (which might be surprising, I know). And [:nonascii:] is only defined for multibyte characters. > (By the way, you may want to fix a trivial typo in a doc string in > rx.el while you are at it: `indian-tow-byte') Done, thanks.
