It would be easily fixable if CommandlineToArgvA was obtaining the command line itself. Then instead of converting to ANSI and then parsing that, it could parse args in Unicode, and then convert argument by argument to ANSI. The output would be ANSI compatible, but split and unescaped in the true form. Unfortunately, the parsing is a two-step operation, with the application calling GetCommandLineA itself first and passing that to the parser, so a fix would need a hack to correlate the versions of the command line input without breaking when it's given a different string.
