utf8 on the Mini6410?

Hey,
how to get utf8 at the console on the Mini?
I have an application that needs utf8! I can not do any masking or anything
else, I am need utf8. I have an rfid reader and the rfid-tokens containing
chars like äöü. And for string comparison I need the correct string with
this chars:-)
What have I to do to get this working on the Mini? Yes, on my pc (Gentoo)
it is running correct.

Thanks and greets from Germany:-)

Try:
export LANG=de_DE.UTF-8
export LC_ALL=de_DE.UTF-8

It may be helpful to know which distribution you are using :)
