console freezing after (bad)key (char) pressed

Hello i have problem with console it freezing when I press some keys
such as: +ěščřžýáíé
I have czech keyboard layout, but it happend to me when I changed to eng. layout and pressed something
situation:
server running
I'm typing commands
everything ok
Now I misstyped some of +ěščřžýá instead of numbers (shift+123456)
then I get error => I can write into console anymore, but server still running
error and console:
