Ok, I have a practical suggestion for you: why don't you have a look
to our testsuite? gcc3.4.0 is shipped with a rich testsuite exercising
of course the functionalities that you need: just take inspiration
from those snippet. In particular, I suggest those in the dir:

  libstdc++-v3/testsuite/22_locale/codecvt/out/wchar_t

Please, try to work out something yourself. In case, we can then help
you if something unexpected happens.
