Unicode::check
public static function Unicode::check
public static Unicode::check()
Checks for Unicode support in PHP and sets the proper settings if possible.
Because of the need to be able to handle text in various encodings, we do not support mbstring function overloading. HTTP input/output conversion must be disabled for similar reasons.
Return value
string A string identifier of a failed multibyte extension check, if any. Otherwise, an empty string.
