AW: Zsh line editor backwards delete

[Dieter Bolz <franz.dieter.bolz@xxxxxxxxx>]

Hi Bart

Thanks for the quick answer.

• The most likely cause of this is that the display width of characters
• in your prompt is not being correctly measured.
  

I just tried it again with setting PS1 to ">" only. 

And now this it works perfectly. So that was the problem.

I will have a closer look at what you proposed now.

  >> db@machine➜    1

My bad!!! It edited that (which I should not have done, as this just pointed you to the problem) manually.

Regards

Dieter

The most likely cause of this is that the display width of characters
in your prompt is not being correctly measured.

What's going on here with the prompt changing?

I suspect you need to adjust your PS1 value to specify a correct
character width for that ➜ glyph.  Search for "glitch" in the manual.
