That's completely unrelated --- it's talking about making correct use of
Windows' locale support in one small bit inside the server.
To make libpq UTF-16 capable, we'd have to change its API for all
strings; either make the strings counted rather than null-terminated,
or make the string elements wchar instead of char. After that we'd
have to hack the FE/BE protocol too (or more likely, require libpq
to translate UTF-16 to UTF-8 before sending to the server). I don't
foresee anyone doing any of this, at least not in the near term.
Putting a UTF-16 to UTF-8 translation in front of libpq seems a lot
more practical.
