Pattern: Use of default Iconv/Mbstring function
Issue: -
Detects calls to Iconv and Mbstring functions with the optional $charset/$encoding parameter not set.
The default value for the iconv $charset and the MbString $encodingparameters was changed in PHP 5.6 to the value ofdefault_charset, which defaults to UTF-8`.
Previously, the iconv functions would default to the value of iconv.internal_encoding;
The Mbstring functions would default to the return value of mb_internal_encoding().
In both case, this would normally come down to ISO-8859-1.
PHP version 5.6
