First, set the local to something that is UTF-8:
set LC_ALL=en_US.UTF-8
Then enter some text that uses a >127 char like: (don't press enter)
echo "zufälliger Text"
Then use delete to back up over the chars, and bash will delete one too many characters. Since you end up with a broken UTF-8 char, if you simply backspace over the extended char, it's difficult to tell what one has...
