Standard `main` has `char` arguments, by Windows convention encoded in Windows ANSI, which generally means data loss and e.g. that some file names can't be passed. Microsoft `WinMain` provides the arguments part of the command line, in Unicode, but not split up into individual arguments.

D should pass the command-line args as properly translated UTF-8. If this doesn't happen, consider it a bug. Regarding Windows specifically, D currently gets the args via GetCommandLineW(), so if that doesn't muck things up then all should be well.
