We currently assume that VMX files are UTF-8 encoded (that's true for
ESX, at least I didn't find a counter example yet), but for example a
Windows based GSX server uses Windows-1252 encoding by default. This
is denoted as .encoding = "windows-1252" in the VMX file.

I'm working on it.

Thanks, pushed.
