$ localectl

and the kde konsole shows german Umlaute as expected.
But after changing to the linux Konsole, for example with Ctrl-Alt-F2,
the german Umlaute öäüß are not shown correctly.
Typing 'loadkeys de-latin1' fixes the problem.
However, this is a bug - Fedora 20 for example configures
the keymap correctly.
Does someone know how to reconfigure CentOS, such that
it enables the german keymap at startup?
