command "cat /etc/localtime" breaks output on tty-terminal

[bitfreak25]

OS: Arch Linux 5.1.12-arch1-1-ARCH (tty1)
Bash-Version: 5.0.7(1)-release
localization: de_DE.UTF-8 UTF-8
keymap: de-latin1-nodeadkeys

Description:
The command "cat /etc/localtime" was called in a tty-terminal. After that some 
characters will be printed incorrectly (mostly "cyrillic" chars instead of the 
correct ones). The typed chars seems to be handled correctly (e.g. calling 
"exit") but the output is broken at this point. This behaviour is reproducible 
on my other PC with Debian Stable (Bash-Version in Debian: 4.4-5), so it seems 
to be a old bug. Changing to another tty or rebooting the OS will fix this 
behaviour until the command is called again.

Kind regards,
