To make it consistent remove the WCHAR cast 3 lines above.
Casts are *not* there to show a conversion is intentional. They tell the
compiler to STFU and to the human reader they mean "*WARNING* doing
something odd here". So don't cry wolf when there's no wolf in sight.

No clue anyway why MSVC even warns, integer to integer conversions are
allowed. If you still want to get rid of those warnings the fix would be
to change the type of charCode to WCHAR. To correctly unmarshal the
WCHAR out of the WPARAM when passing it to ME_Char() use LOWORD().
