Just as a note, it sometimes shows as 1-wide on Nerd Fonts

Interesting. So, this is a full-width Windows logo, or it's supposed to be.

(this is what it looks like with JetBrains NF: image)

The character there looks like I copied U+8005

But I'm not sure that's a supported NF codepoint:

From those results:

  • f17a -  - this works as a single-width in the Terminal for me
  • e70f -  - same, this works as a single-width in the Terminal for me
  • fab2 - 者 - This one repros the "the icon is single wide, but the Terminal thinks it's double wide"
    • Of course, U+FAB2 does look double wide, so that makes sense

I can't find anything myself in starship's docs about where they'd set up the prompt to display the Windows icon as a default. Did you do something to configure starship manually with that icon? Do the other versions of that icon work?

@zadjii-msft Yes, it’s a configuration I made, specifically an environment variable.

I will also note that it’s fixed with a Zero-Width character before, though it adds a space(?)

I tested it elsewhere and it always was 1-wide with Nerd Font.

I will just change the icon.

Right, so the issue here is that Nerd Fonts is using ranges of characters that it should not be using. U+FAB2 is officially declared as being "full-width", and so any compliant terminal emulator will render it as two columns.

That codepoint is a "CJK Compatibility Ideograph". Nerd Fonts is incorrect to assign a Windows logo to that codepoint.

We have some rendering issues when zero-width and multi-width characters are placed next to eachother, but we're tracking those issues over in #8000 and (a different issue as well, I can't find it right now).

Thanks for clarification! It wasn’t really an issue with Windows Terminal after all…
