--- Comment #5 from Henrik Krohns <apa...@hege.li> --- I tried performance tests with mass-check, there's absolutely no difference here for normalize_charset, total duration was always within normal +-2% variance. Rule differences between these were mainly: __HIGHBITS MPART_ALT_DIFF_COUNT TVD_SPACE_RATIO __freemail_safe_fwd As we can see from __freemail_safe_fwd, if normalize is on, we can't assume that a single dot will match a character like "รค".. committed (?:\xe4|\xc3\xa4) fix for it. Question arises whether regexes should be run with unicode semantics (. = single character) instead of matching raw bytes. Have to investigate if the others need fixing. -- You are receiving this mail because: You are the assignee for the bug.
