Well, maybe I'm missing something, but it never converts input characters
to UCNs so that means it doesn't do (A) or (B), and the only thing it
converts to wide characters are wide string literals, so it doesn't do
(C).
Hmm... maybe it's doing (B) if UCNs aren't ever necessary, though it
doesn't seem to support extended characters in indentifiers so it's not
quite using native encodings where possible. Though the intent does
seem to be to go with option (B).
