i18n: encode output in user's local encoding This makes the translated output obey the HGENCODING environment variable or the preferred encoding as set by the LANG or LC_ALL environment variables. Python 2.4 has a lgettext method which is similar, except that it doesn't know about HGENCODING or the settings in .hgrc.
