Re: UTF16 <-> UTF32

Today I needed conversion functions from UTF32 to UTF16 and in the
opposite direction. I wanted to allow result-string re-usage and
decided to give the result string as a reference-parameter. This
would help the result string to keep its capacity.
I think there's no way to implement that code faster.

It uses iconv(3).  No warranty implied.
