This is confusing:
(When surrogatepairs are used when the server encoding is <literal>UTF8</>, theyare first combined into a single code
pointthat is then encodedin UTF-8.) 

So something else happens if encoding is not UTF8?

I think this part can be simply removed, it does not add anything.

Or say that surrogate pairs are only allowed in UTF8 encoding.
Reason is that you cannot encode 0..7F codepoints with them,
and only those are allowed to be given numerically.  But this is
already mentioned before.
