Locale environment for user root not set to UTF-8
A default install of Backtrack 4 with USA set as location and English as language only sets en_US.UTF-8 for the user created during installation. Therefore when one tries to login as root and type with a different keyboard layout than the default for USA in Konsole, certain characters such as "ċäö" will not be displayed.
There are several ways to correct this, but the one that I find easiest is:
1. open ~/.profile
2. change these lines:
3. logout (not only from x)
Enjoy UTF-8 in Konsole under root!
