[ESS] encoding of i/o in *R* buffer and norwegian letters

[Mathieu Basille]

Hello Jarle

I'm not sure what's your problem, however, I don't have this kind of 
problem with Ubuntu 6.10 and Emacs 23 from the depository of Alexandre 
Vassalotti (http://ppa.launchpad.net/avassalotti/ubuntu/).

Everything work in utf-8. I have this line in my .emacs, in the 
custom-set-variables :
  '(current-language-environment "UTF-8")

By default, files are encoded in utf-8, and R as well works in utf-8. 
When I use the expression you gave us :

 > cat("ø\n")

I have the correct behaviour :

 > cat("ø\n")
ø

both from the R buffer directly and from a .R file.

Hope this helps.
Mathieu;
