Before I started this project I asked where to put the functions:
http://www.winehq.org/pipermail/wine-devel/2012-January/093705.html

I received no reply, so I put them in libwine. Then I was told to move
them to kernel32:

MSDN states:

"Starting with Windows Vista, this function fully conforms with the
Unicode 4.1 specification for UTF-8 and UTF-16. The function used on
earlier operating systems encodes or decodes lone surrogate halves or
mismatched surrogate pairs. Code written in earlier versions of
Windows that rely on this behavior to encode random non-text binary
data might run into problems. However, code that uses this function on
valid UTF-8 strings will behave the same way as on earlier Windows
operating systems."

My implementation is modeled after Windows XP (Wine's default target
Windows version), which encodes and decodes arbitrary character
sequences without normalization. I saw that my submission has already
been marked "rejected"--was this why?
