I'm not sure what you mean by "Japanese". It's no problem at all
to use UTF-8 to write Japanese. And I guess if somebody uses
\u literals and wants default_internal  to be UTF-8, they'll
in most cases use UTF-8 for the source encoding (comments or
whatever else).

If you mean Japanese legacy encodings (such as Shift_JIS and
EUC-JP), then your are correct, but it would be very rare
for somebody to use Shift_JIS or EUC-JP for comments when
the program is otherwise supposed to run all-UTF-8.

Well, yes, that's actually the point of it. Wherever necessary,
get everybody to declare their encoding. It may be somewhat suboptimal
in the transition phase, but after that, we know what we're dealing
with.
