Title: Update upload/system/library/request.php

Default encoding for the htmlspecialchars function is ISO-8859-1 in versions of PHP prior to 5.4.0, and UTF-8 from PHP 5.4.0 onwards. Better if encoding is always specified to UTF-8. I think this is what may have caused "broken" settings in modules (like in welcome module) etc. resulting in error messages like "Notice: unserialize() [function.unserialize]: Error at offset 58793 of 65535 bytes in admin/index.php"
