As far as I know UTF-7 is very similar to UTF-8, using only 7 bits per 
byte instead of 8, or something similar, it's meant for compatibility 
with systems that don't like use of the full 8 bits. UTF-16 is a 16bit 
encoding. I don't know whether Windows NT's wide characters are meant to 
be UTF-16 or UCS-2 (also 16bit, but without the ability to encode 
characters that need more than 16bits to encode), but my guess it uses 
one of those.
