[Bug 48174] wine-mono creates incorrect strings

--- Comment #5 from Vincent Povirk  ---
What I mean is that Mono's StringToHGlobalAnsi is using utf8 when it probably
should be using CP_ACP (and I believe it does currently use its own code to do
the conversion).

I'm just trying to figure out and give a complete explanation (and hopefully
fix) what's happening. I'm not necessarily giving you advice or trying to say
the program is wrong. Obviously, it works on Windows, so we're almost certainly
doing something wrong.
