[PCL-CVS] Interactive diff on a utf-8 encoded file

[Jérôme Haguet]

Hello
I have
- GNU Emacs 21.3 on Windows
- a CVS checkout in which most of the files are encoded in ISO-8859-1 and
some others in UTF-8.

All the utf-8 encoded files have the .utf extension
I have added in my .emacs the following line :
(add-to-list 'file-coding-system-alist (list "\\.utf" 'utf-8))
prefer-coding-system is set to 'iso-latin-1

Everything works fine when I open a file (Emacs set the right coding system)

My problem is when I run interactive diff from PCL-CVS (d e)
Emacs always set the coding system of the BASE version of the .utf files to
iso-8859-1

Any idea how to fix this ?

Thank you in advance.

Jérôme
