Please describe the problem:
When replying to a post, I can't influence the language in which
the line ''Hynek Hanke wrote on the 30th of June...'' will appear?
Locales is really inappropriate as this concerns the language of the
recipient, or more precisely the language of the message, not the language of the system of the sender. This is VERY annoying, especially because if I keep the line in Czech (my language and my locales), recipients will get character from my language set which they likely do not have the necessary fonts for. It is also especially annoying in communication on mailing lists where this line is really necessary so that others can easily see who do I quote in my reply. Under the current situation I have to type in this line manually most of the time I hit the reply button. Same for the header included if I hit Forward.


Steps to reproduce:
1. Set locales to Czech and reply to an English mailing list in English.

1. Set locales to English and reply to a German messge of your German
friend in German.

etc.


Actual results:
A line is included at the beginning of the message with a language that I can't influence and which is many times totally inapropriate, quite likely to be ununderstandable to the recipient and contains characters from a different character set (in my case iso-8859-2, but it could be worse, consider a user from China], etc.

Expected results:
One option would be to default the header to my locale, but provide a bar which lets me choose the language I want to use in this particular case. Or it could let me choose from several options which I set up in my configuration.

Does this happen every time?
Yes. It is however only a bug when I'm not writing in my native language (most of the time).
