Character position twisted

[soaringk]

Current Behavior

The characters shifted somehow when I press the Tab to complete the command.

And it also happens when I try to move my cursor.

Another weird behavior is that the cursor will quickly fall back one position after finishing initialization.

Steps to Reproduce:

1. download prezto and follow the instruction
2. change zstyle ':prezto:module:prompt' theme to powerlevel10k

Context (Environment):

OS: macOS Catalina 10.15.5
Terminal: iTerm2, Terminal.app
manager: prezto

Detailed Description

This happens when I updated the powerlevel10k to the latest version.
I tried to record the screen using terminalizer, but it work smoothly in the rendered gif... I've no idea.

Did anyone get this problem?

1. What is the output of typeset -p TERM?
2. Have you tried following https://github.com/romkatv/powerlevel10k/blob/master/README.md#cursor-is-in-the-wrong-place ?

Thanks, I solved it by run p10k configure after installing the recommended font.

Well, this is probably caused by the ip, because when I uncomment this element, the same problem occurred.

I also tried to restore a backup and comment this element. Problem solved.

Any idea?

What is the output of the following command?

print -r -- ${icons[NETWORK_ICON]}

\uF877

Thanks, I observe this:

I tried to fall back to some old image, I get this from the following.

Maybe something breaks after the v1.12.0?

If you want to show how it looks, you'll need to post screenshots. Posting just text doesn't work because my browser can render it differently from your terminal. Note that you don't need to censor the IP because it's on a private network.

If prompt is shorter/longer than the frame, you can find out which symbol is causing issues by copy-pasting a part of the prompt.

Also please follow the guide I linked above and try what it suggests. E.g., verify that you don't have the awful iTerm2 option to display ambiguous characters as double width turned on.

Thanks for reply.
I didn't turn on the 'Ambiguous characters are double-width' on iTerm2.

I found out the last character was considered as double width

However, when I tried copy and pasting the character one by one, I found this.

I also tried the same thing in a docker image I built a while ago.

print -r -- ${icons[NETWORK_ICON]}

As for this command, I get this in container:

So the problem is that your terminal incorrectly displays \uF877 as a zero-width character. This character is from Private Use Area, so it must be displayed as single width. This is the same macOS low-level bug as in #241. You can follow the same instructions as in #241 (comment) to verify this (simply replace F878 with F877).

I'll need to change the default icon used by ip segment. It's unfortunately that I don't know which range of characters is affected by this macOS bug, so it's not clear which icon is safe to use as a replacement. Perhaps \uF50D? Can you verify that your prompt gets fixed if you add the following parameter to ~/.p10k.zsh?

typeset -g POWERLEVEL9K_NETWORK_ICON='\uF50D'

By the way, https://github.com/romkatv/powerlevel10k/blob/master/README.md#if-the-prompt-line-is-shorter-than-the-frame-and-is-mangled already describes your case. I wonder what could be made clearer so that you could identify it yourself.

typeset -g POWERLEVEL9K_NETWORK_ICON='\uF50D'

Sorry, I didn't know much about the encoding. I checked #241 and this is the result.

So I thought this is caused by:

This can also happen if prompt contains glyphs designated as "wide" in the Unicode standard and your terminal incorrectly displays them as non-wide. Terminals suffering from this limitation include Konsole, Hyper and the integrated VSCode Terminal. The solution is to use a different terminal or remove all wide glyphs from prompt.

instead of a macOS low-level bug.

Maybe provide an example like typeset -g POWERLEVEL9K_NETWORK_ICON='\uF50D' could be helpful? It would be more straightforward if users can just see the difference themselves.

I don't understand. Let's forget that I've asked this question.

I've replaced the default icon. Since you are using prezto, you won't pick up this fix until the next powerlevel10k release. You can keep POWERLEVEL9K_NETWORK_ICON in your config until then. Once you get the new version of powerlevel10k, you can remove this parameter.

[soaringk]

I think I misunderstand the solution in #241. I should be able to identify the problem.

Thank you for your reply.
