Does using /u modifier in PCRE cause any problemm if unicode is not used?
/u modifier is used in PCRE when we use unicode characters like /x{0xFF0}.
Does it cause any problem if we have a regex like /^\d{10}$/u (e.g. using
unicode modifier when unicode is not used in regex) ? I ask this because I
get different results in localhost and production server(using preg_match
function)
And if it doesn't cause any problem, why this modifier is not used by
default?
