[Message part 1 (text/plain, inline)]

In current implementation, 'japanese-iso-8bit' is used as prefered
coding system when you select 'Japanese' as language environment on
Unix system. But nowaday a lot of Japanese Unix users adopt
'ja_JP.UTF-8' as locale setting. So I propose to change prefered
coding system from 'japanese-iso-8bit' to 'utf-8'. And while I'm on
it, comment is fixed to fit current implementation.

Subject: [PATCH] Change prefered coding system for Japanese language
 environment.

* lisp/language/japan-util.el (setup-japanese-environment-internal):
  Use utf-8 as prefered coding system instead of japanese-iso-8bit
  when system is not windows. And while I'm at it, fix comment to fit
  current implementation.
