The people from the SG16 in the committee think it is and are preparing a 
paper to clarify. They came to the same conclusion regarding the steps the 
compiler performed as you did, but those steps still lead to an absurd result. 
Why in the world would anyone want the UTF-16 representation of the UTF-8 
encoding of something?

The point is that the compiler had 0xC4 0x82, knew it was UTF-8 and was being 
asked to provide an UTF-16 representation. It should have performed a UTF-8-
to-UTF-16 transformation, not CP1252-to-UTF-8 one.
