Er, RMI objects should be sent using no encoding... that is, serialized
objects encode themselves. For java.lang.String, the serialized form is
always in UTF-8. From section 6.2 ("Stream Elements") of the java
serialization protocol:
"
The representation of String objects consists of length information
followed by the contents of the string encoded in modified UTF-8. The
modified UTF-8 encoding is the same as used in the JavaTM Virtual
Machine and in the java.io.DataInput and DataOutput interfaces; it
differs from standard UTF-8 in the representation of supplementary
characters and of the null character.
"
There should be no concern with RMI, here.

He doesn't say whether he's using RMI, but my guess is he isn't. I
suspect he's using something ad-hoc.
