Hmm, are you sure this would make the encoding declaration a
popular tool ?

If we would just allow ASCII-supersets as source file encoding,
then we wouldn't have to make that restriction, since only the
Unicode literal handling in the parser would have to be adjusted
(and this is easy to do).

This would make UTF-16 encodings impossible, but I think that
two-byte encodings not the right approach to maintainable programs
anyways ;-)
