"Double-byte character" is a really, really vague term. It depends 
completely on what specific character encoding you're referring to. I'll 
assume you mean Unicode. The Jabber protocol uses XML, which supports 
Unicode, and in fact the server and all(?) clients use UTF-8 encoding, 
which allows the full Unicode character set to be represented. Of 
course, how much of that character set can be represented in the UI 
depends on the quality of Unicode support in the client's OS and the 
available fonts. I've recently seen some problems with X-Windows based 
clients misinterpreting curly quotes as underscores, for example.

PGP is used by clients to encrypt messages sent between them.  The 
details of how it's used depend on the clients. The server does not use 
PGP or interpret PGP-encoded messages at all; it just transmits the 
encoded bytes.

I'm not sure exactly what flavor of PGP encoding is defined by the spec 
for inter-client communication; the protocol documents I've seen are 
unhelpfully vague on that point.
