In this case, you should mUTF-7 encode the string (your client should be
doing this for you).

GOODCHARS is indeed much more conservative than it needs to be (we tend to
be careful around anything that might cause someone trouble -- especially
in shell scripts).  However, you are still limited to 7bit characters
(which is why you should use mUTF-7).
