Attached is a UTF-8 aware version of the `addquoted` function.  I'm not sure if it really fits given that the UTF-8 behaviour is attached to a different library, but it might be useful to someone and it's better than my last proposal.

Also, I have noticed that the `utf8_decode` function passes the UTF-16 surrogates which are illegal codepoints, so this might also need to be fixed.

Duane.
