ZSH Autosuggestions Creates Duplicate Characters	2022-06-28	Software	software fix

I have noticed that sometimes the zsh-autosuggestions plugin repeats characters after using tab-completion. This happens when the locale environment variables are not set correctly (a detailed explanation can found here).

The environment variables can be set persistently in /etc/default/locale for Ubuntu systems. My setup looks like

LANG=en_US.UTF-8
LC_TIME=de_DE.UTF-8
LC_MONETARY=de_DE.UTF-8
LC_PAPER=de_DE.UTF-8

For my Ubuntu server I realized that the settings in /etc/default/locale have been ignored. This can be avoided by setting UsePAM yes in /etc/ssh/sshd_config. For Debian this would be the default setting.
