Unless you have told it otherwise, omniORB is using UTF-16, not UCS-4,
even if your platform has 32-bit wchar_t. I assume you aren't using
characters outside the 16-bit plane?  If you are, and you haven't
chosen UCS-4 by setting the nativeWCharCodeSet parameter, that would
explain the problem. If you have explicitly chosen UCS-4, characters
outside the BMP (Basic Multi-lingual Plane) should be properly
transformed into UTF-16 surrogate pairs. I don't think Java deals with
surrogates, though. Anyway, I don't think that's relevant to you.

Please can you give an example of the code points you send and the
code points you receive. Please also post a trace from omniORB with
arguments -ORBtraceLevel 40.
