I think the problem is that we've not told libcpp what the correct
narrow character set is. I suggest adding something like
if (BITS_PER_UNIT >= 32)
cpp_opts->narrow_charset = BYTES_BIG_ENDIAN ? "UTF-32BE" : "UTF-32LE";
else if (BITS_PER_UNIT >= 16)
cpp_opts->narrow_charset = BYTES_BIG_ENDIAN ? "UTF-16BE" : "UTF-16LE";
in a likely looking place in c_common_init_options. Then you
shouldn't have to do any translation in your output routines
at all.
