Exactly what Windows does for what?  Recognizing a utf-16 registry file when 
opened in the registry editor?

I don't recommend binding .reg to a single encoding.  All Windows registry 
files use the .reg extension, but there are two formats.  For Windows NT and 
older, registry files are encoded in the OS's locale-specific character set 
(for English, cp1252).  For Windows 2000 and newer, registry files use utf-16.
