Hi,

I'm using Gnus/5.13 in Emacs/23.0.60.1 in Gentoo GNU/Linux. My 'LANG'
environment variable is set to 'C' . And I've following line in my
~/.gnus:

(setq gnus-default-charset 'utf-8)

My .signature file contains some UTF-8 encoded text. Now, when I post
- From Emacs running in X, my messages were sent as UTF-8 encoded,
whereas when I sent from Emacs running in xterm, all my messages were
sent as ISO-8859-1 encoded. Any ideas, what is wrong ? Although in xterm
I don't expect to see, non-ASCII characters rendered, but changing of
message encoding is unexpected.

BtW, From: header of my mail also contains UTF-8 encoded text, but it
doesn't get affected by this.

Any ideas, what is wrong ? And what is the solution ? At the moment, I'm
typing this message in Emacs running in an xterm.

TIA
