Comment(by azaozz):

 PCRE UTF-8 (the "u" modifier) is not supported everywhere. For reference
 see  wp_check_invalid_utf8(). We probably could set a global instead of
 the static there and use that for the three functions since they are
 usually called multiple times.

 In any case this will need testing in an affected locale/installation.
