Question

Here is what I use:
– MacOS X 10.6.7
– GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin10.0)
– Mercurial Distributed SCM (version 1.7.2+20101201)
– GNU Emacs 24.0.50 (build from git repo with –cocoa flag)
– aHg v0.99

Here is my emacs settings:

(set-default-coding-systems 'utf-8)
(prefer-coding-system 'utf-8)
(setq locale-coding-system 'utf-8)
(set-terminal-coding-system 'utf-8)
(set-keyboard-coding-system 'utf-8)
(set-selection-coding-system 'utf-8)
(set-language-environment 'UTF-8)

And here if what i got after C-c h g s:

parent: 2512:6252abcd7368 tip
 JavaScript: ???????? ???????????? ????? ? ???????.
branch: default
commit: 3 modified, 6 unknown
update: (current)

Running hg log under M-x term gives me a correct result I can read (? is a russian chars…). So… How can I fix this in Emacs in aHg output?

Answer 1

First thing, that should be checked here – which LANG is set when Emacs was started)? (what is returned when you execute M-: (getenv "LANG")? As I remember, Mac OS X set LANG to “C” on the start of launchpad… setting of language environment don’t modify LANG…

You can explicitly set the LANG environment from Emacs using (setenv "LANG" "ru_RU.UTF-8") or use “en_EN.UTF-8” if it preferable.

P.S. I just checked ahg with different LANG settings, and see question marks when I set LANG to “C”, and see Russian letters when I run ahg-log in repository
