RH9: iconv error

[Cornelius Kölbel <cornelius koelbel gmx de>]

Hello,

I had several problems with utf-8 codes. Many programs did not run, due 
to the definition of utf-8.
After changing my /etc/sysconfig/i18n and removing every utf, these 
program run ok.

But now I get problems, when invoking man-pages:

iconv: ungültige Eingabe-Sequenz an der Stelle 311

Unfortunately it is in german, but I hope, someone can help.
It is something like
iconv: ivalid input sequence...

How does he wants to convert the manpage?

Regards
Cornelius
