problem with UTF-8 when accessing Emacs installed on iMac from ssh session on the iPad

problem with UTF-8 when accessing Emacs installed on iMac from ssh session on the iPad

[Carl Bolduc]

I have Emacs 23.3 installed on my Mac and it works perfectly there.

I use Emacs on many platform so I keep all my text file in UTF-8, I
have this in my .emacs: (prefer-coding-system 'utf-8)

On the Mac, I can open a terminal and run Emacs -nw and all the characters work.

On the iPad, I use Prompt
(http://www.panic.com/blog/2011/04/introducing-prompt-ssh-for-ios/) to
open a ssh session on my Mac and run Emacs remotely. Whenever I try to
add a "French" character such as "é" or "è", I get "\351" in the
buffer and Emacs will complain if I try to save the file. If I switch
the coding system to iso-8859-1, I can enter the French chars without
any problems.

Is there a setting I can change to make UTF-8 work when I access Emacs
through ssh?

Carl

Are you saying that existing text is displayed correctly, and the
problem is with typing French characters?  If so, please tell what
does the following display in Emacs:

  M-: keyboard-coding-system RET

Also, is this a GUI (graphical) session or a text-mode session?

Yes, existing text is displayed correctly, and the problem is with
typing French characters.

The result of the eval is: utf-8-unix

I have this in .emacs:
(setq locale-coding-system 'utf-8)
(set-terminal-coding-system 'utf-8)
(set-keyboard-coding-system 'utf-8)
(set-selection-coding-system 'utf-8)
(prefer-coding-system 'utf-8)

It is a text-mode session (Emacs -nw through SSH).

Looks like Prompt doesn't support UTF-8 keyboard input?

If you can go with setting keyboard-coding-system to latin-1, that
will do.  Failing that, I guess my next suggestion would be to use
Emacs input methods (C-u C-\).
