description "Detects the character set of a page, this is required for MongoDB output. Only checks the meta content tag, not the HTTP header. It tries the specified charset, then ascii, then utf-8 then uses CharDet from the rchardet gem which is CPU intensive / slow. Tests conversion to UTF-8 using Iconv. Returns Failed if unsuccessful."
