Many of the windows APIs use UTF-16 without validating it.  They'll
pass through invalid strings until they hit something that does
validate, at which point it'll blow up.

I suspect that it doesn't happen very often in practice, as having
only one encoding makes it quite clear that it's a broken file name,
not a mixed encoding environment.
