You shouldn't need to handle this case separately. You have even added a
test that shows that LCMapStringEx(..., LCMAP_UPPERCASE, buffer
containing 0x131, ...) should not change 0x131 character. It should be
fixed somewhere else (if needed toupperW may be changed to e.g.
LCMapString call).

Thanks,
Piotr
