Some characters are shown as squares in v0.33.1

[0x7a7a]

After yesterday's update(0.33.1), I realized that the which-key plugin icon in my Neovim was showing up as a square,but it displays correctly in editors and terminals.

I've mapped nerd fonts in kitty's configuration with symbol map, and it worked fine before.

I'm using macOS, and looking at yesterday's changelog there are a lot of character related update, so I'm wondering if there's something wrong.

I tried rolling back to version 0.33 and the problem was solved.

If there is any other information you need, please let me know,thanks!

Below is a screenshot of the problem:

I need to know which characters there are as in their unicode code points. Which you can get by pressing ga in vim with the cursor over the character. Once you know which character run

kitty --debug-font-fallback zsh -c 'printf "\uABCD"; read'

replace ABCD above with the hex code for the character and post the output.

To be clear is it not rendering with the above? Because it renders fine for me. With default configuration. Which font exactly is hack? And if it is not rendering, does it render without using Hack?

[medicm]

Yes, I have also noticed when upgrading from 0.33.0 to 0.33.1 that Symbols Nerd Font starts rendering as blocks.

To be clear is it not rendering with the above?

I don't think it's unrenderable, because it's not a problem in kitty's version 0.33.

Which font exactly is hack

The Hack font is a little old, but it's always worked well before.

does it render without using Hack

I've tried other fonts, but the problem is still not solved.

[kovidgoyal]

I think the issue is caused by the Zapf Dingbats font. Try removing it from your system temporarily to confirm.

[0x7a7a]

This is the result of running in v0.33

[kovidgoyal]

The changes in 0.33.1 to try to get coretext to return fallback fonts matching the bold/italic attributes are for some reason causing it to return Zapf Dingbats on your systems. Which doesn't actually contain those codepoints.

[0x7a7a]

It's a system font that can't seem to be removed.
I'm worried that forcing it to be removed will have an effect on other programs.

[kovidgoyal]

its a font, it cant cause any problem beyond some charactes not
rendering. Do something like

sudo mv /System/Library/Fonts/ZapfDingbats.ttf /tmp

run the test

and move it back.

This operation seems to be interfered by the System Integrity Protection, unless I disable the SIP and reboot.

I can try. I'll have to get back to you.

I currently haven't the time, but you have to disable system integrity checks to do that
