The above output indicates that something seems to be wrong with your
locale settings.

Can you please post the output of the command "locale"?

Does the problem go away if the respective locales are generated?
You can have them generated by running the command "dpkg-reconfigure"
(with root privileges) and selecting the corresponding locales. (The
above output suggests that those are "cs_CZ.UTF-8" and "en_US.UTF-8" in
your case.)
