[Bug libgcj/31939] New: Command line arguments are byteswapped before being passed to the program runing in custom locale.

[serg at vostok dot net]

Conversion to UCS-2 encoding in GNU libiconv returns bytes in network
order. gcj wants to have them in host order. The hack in libgcj swaps bytes
when necessary. However, command line arguments slip by the swapper (or
go through it even number of times).

This produces unrecognizable for a program command line arguments. There is a
non-zero probability of this producing invalid UTF-16 strings, e.g. with
unpaired surrogates. That, in turn, may result in segmentation faults during
string operations, especially I/O character encoding conversion.
