I read the post above and noted that the patch has been applied. I think
it is not a good idea.

The patch is not a general approach to handle different encodings.  It
is a hack to force AUCTeX to work in Japanese encoding.

Secondly, isn't it better for the user to add

%% Local Variables:
%% coding: iso-2022-jp
%% End:

or any other encodings in their .tex files? And if that encoding is
preferred maybe even:

 (prefer-coding-system 'iso-2022-jp)

What do you guys think?

Best wishes,

Leo
