tr broken with accented chars

[thomas]

Hello
I have a problem with tr, version 5.94 :

address@hidden:~$ echo hello | tr o a # no problem here
hella

address@hidden:~$ echo hé | tr é e # why do I get 2 'e' ?
hee

address@hidden:~$ echo hé | tr à a # here tr should do nothing...
ha(c)

I'm using debian with a 100% utf-8 system. It is not an x-term related
problem (this also occurs in a vt). Quoting the arguments (tr "é" "e")
does not help.

Thanks a lot for your help
