A class with non-ASCII runes matches them: [éa-z] is taken as (é|[a-z]), a range up to 256 runes spelled out

mvzr's classes hold bytes, and it refused a multibyte member as a bad expression. Rewriting the class before compiling, as ^a|^b already is, needs no mvzr patch; runes that differ only in their last byte go as one alternative (\xc3[\xa0-\xbf] for [à-ÿ]) so a 256-rune range fits the 512-operation limit, which counts the pattern as rewritten. A wider range and [^é] are refused, naming why.
