Taking the list of characters that mysql_real_escape_string() says it escapes:

does not work properly when used with a multibyte encoded string.
That is most likely the reason why my

How can I configure mysql_real_escape_string() to _not_ need a
database connection in order to do it's work on a string. I understand
that the function wants a database connection to determine which
charset / encoding is in use, but in my case it will always be UTF-8.
