server encoding

OK, that makes sense for storing the data. What about parsing the
commands? The protocol spec doesn't seem to specify any specific
encoding to use. I've browsed through some client implementations -
the Java and C# stuff use UTF8, the Ruby and Perl don't seem to
specify. I guess I'll use UTF8 for everything but the actual data,
keeping that as a byte[].
