bash: $'\302\211[COMMAND]': command not found

Question

I've used bash in xterm on Debian Jessie for about 2 years. Just recently I sometimes get an error bash: $'\302\211[COMMAND]': command not found.

The only help I can find on the topic is Piping grep causes error $'\302\240grep': command not found on linux and Why do I sometimes get sh: $'\302\211 … ': command not found in xterm/sh?. This sometimes happens when I type tab for command completion. Is there any way I can get rid of this without switching terminal emulators?

Answer 1

This is the same problem as Why do I sometimes get 'sh: $'\302\211 … ': command not found' in xterm/sh? (but not a duplicate — yet — because there was no suitable answer).

Summarizing from my answer: you see this behavior because occasionally you press metatab rather than just tab, which makes xterm send a different character.

Answer 2

This solve the problem:

setxkbmap -option "nbsp:none"
