This is poorly explained. To begin, cmdproxy, as it was before the
patch, does not support UTF-16. For fixing that, you need to start
by implementing

int wmain(int argc, wchar_t *argv[])

and revise all string handling from there. The workload the patch adds
for migrating cmdproxy to UTF-16 would consist on
s/_snprintf/_snwprintf. Not doing that would cause compilation errors.
