Yes, on that, I was thinking to only use wchar_t in wmain just to get the arguments properly (not destroyed), and immediately convert to UTF-8 char arrays to pass to the rest of the program (starting with the call to driver.main which main wraps). That way, all sources would stay the same working with char arrays, only this time it would be UTF-8 char arrays that properly carry the Unicode args. This would allow only selected parts of the Windows-specific code (possibly only in libiberty/pex-win32.c) to opt-in for the necessary conversion back to wchar_t UTF-16 arrays in order to call the Unicode versions of Win32 APIs like CreateProcessW etc., and get end-to-end Unicode support on Windows.
