We have in the ISO POSIX WG been thru all POSIX standards to see
what changes we should do to the standards to accompdate UCS.
We found that POSIX standards in general were ready to handle UCS
in the UTF-8 encoding without problems, as the APIs for example
were encoding independent. The null bytes in UCS-2 and UCS-4 was
considered to make problems for many current implementations of
POSIX, due to the null byte being used to terminate strings in
C and C++ programs.

We are working on a new interchange format, where the file names
are to be encoded in UTF-8.
