Hi geeks, Does anyone have a suggestion on how the documentation should be updated? The quote is from here: http://php.net/manual/en/regexp.reference.character-classes.php With the quote being: "In UTF-8 mode, characters with values greater than 128 do not match any of the POSIX character classes." A few simple/related facts: - PCRE_UCP exists as of PCRE 8.10 - Gustavo mentioned the related PHP change on Oct 3, 2010 (not sure what PHP version, and googling for "87a237342" turns up empty, and I miss SVN version numbers) Anyway, how should this be documented? Regards, Philip
