Lua appears to populate package.path to something based on the
executable path on windows, but since it uses msvcrt in ANSI mode,
that string is encoded in whatever 8-bit MBCS is configured by
the host system ACP setting.
Rust expects that to be UTF-8, but Windows doesn't guarantee it.
This commit updates the manifest for wezterm-gui to tell Windows
that it wants its ACP to be set to UTF-8 prior to launch, which
should resolve this situation for the GUI.
This commit also introduces a more cut-down manifest for the
console-subsystem executables that also use the lua config layer,
which should hopefully resolve this issue for them.
This commit was authored on a mac, so fingers crossed that it
even compiles properly on windows!
