As this does not seam to work (always returns "pass"). you can use

$encoding = mb_detect_encoding(urldecode($REQUEST_URI), 'UTF-8, UTF-7, ASCII, EUC-JP,SJIS, eucJP-win, SJIS-win, JIS, ISO-2022-JP, ISO-8859-1');

to detect the encoding of the url instead, similare steps could be taken to deteck cookies and post data although it would have to be done for each value.

"pass" means "no conversion":

See here:
http://php.net/manual/en/mbstring.configuration.php#ini.mbstring.strict-detection

mbstring.http_input           = pass    ; No conversion.
mbstring.http_output          = pass    ; No conversion
