Technically, Windows doesn't violate the standard by having a 16-bit
wchar_t.Â It violates the standard by using a wide execution character
set that defines code points that do not fit in it's (16-bit) wchar_t
type.Â We have an issue (https://github.com/sg16-unicode/sg16/issues/9)
to track modifying the standard to enable Microsoft's implementation to
