True, but in my defense only in the paths we are unlikely to hit.

Looks correct to me, assuming there are no valid UCS2-BE characters
with 0xff in first byte because the length check only checks first
byte.  The 0x81, 0x82 cases now also accept UTF-16 characters that
aren't UCS-2 (with upper byte 0xd8...0xdf).
