Hi again, gmpassos :)

This is what I use: (I didn't write this myself)

# ValidUTF8 came from: http://people.netscape.com/ftang/utf8/isutf8.pl
sub ValidUTF8 {

        local ( $utf8 ) = pop (@_);

        if($utf8 =~ /^(([\0-\x7F])|([\xC0-\xDF][\x80-\xBF])|([\xE0-\xE
+F][\x80-\xBF][\x80-\xBF])|([\xF0-\xF7][\x80-\xBF][\x80-\xBF][\x80-\xB
+F])|([\xF8-\xFB][\x80-\xBF][\x80-\xBF][\x80-\xBF][\x80-\xBF])|([\xFC-
+\xFE][\x80-\xBF][\x80-\xBF][\x80-\xBF][\x80-\xBF][\x80-\xBF]))*$/)
        {
                return ! ($utf8 =~ /([\xC0-\xC1])|([\xE0][\x80-\x9F])|
+([\xF0][\x80-\x8F])|([\xF8][\x80-\x87])|([\xFC][\x80-\x83])/);
        }
        else
        {
                return 0;
        }
}
