Some characters are shown as squares in v0.33.1 about kitty HOT 24 CLOSED

Yes, it's correct, but there is no need, I have pushed the correct fix, see my latest commit.

yes you can, and symbol_map is disjoint in your case anyway, which means it will only use menlo for that codepoint. And no I cant reproduce it. I should note my mac is 14.4 Sonoma.

from kitty.

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?

from kitty.

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

from kitty.

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.

from kitty.

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

from kitty.

This is the result of running in v0.33

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.

from kitty.

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.

from kitty.

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

I've turned off SIP, but I still can't remove the font.

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.

Would such a matching rule bypass the symbol_map configuration?

from kitty.

No, it doesnt. symbol_map has highest priority. hack does not contain U+2726. On my system COreText returns Menlo as the fallback for it. Dont know why its returning Zapf Dingbats on yours. In any case a temporary fix you can use symbol_map to map U+2726 to Menlo

from kitty.

It seems we've had a misunderstanding. You replied to @medicm .

About my character problem I tried to configure U+279C with symbol_map, but it still doesn't match

from kitty.

U+279c not in NERD fonts. You want to symbol_map it to Menlo. And note that the fix in the commit is speculative as I cant reproduce the issue, so YMMV.

from kitty.

And interestingly, all three of ❯✦➜ are present in zapf dingbats as well in my system. So I really have no clue whats going on.

Can symbol_map be configured with multiple fonts?
In my case, I want to configure the nerd font as the first choice, and then match the Menlo, I do not know how to config

And interestingly, all three of ❯✦➜ are present in zapf dingbats as well in my system. So I really have no clue whats going on.

I don't know why, but it's a good start if you can reproduce it 😄

from kitty.

yes you can, and symbol_map is disjoint in your case anyway, which means it will only use menlo for that codepoint. And no I cant reproduce it. I should note my mac is 14.4 Sonoma.

I have the same version of the OS.

Am I configuring this correctly? It seems to be working. I just wanted to make sure.

symbol_map  codepoints  Symbols Nerd Font Mono
symbol_map  codepoints  Menlo

Can you tell me how to determine what fonts the codepoints are in, so I can deal with a similar problem myself next time?
Sorry. I'm a bit of a babbler.

from kitty.

This is great, thank you Kovid!

from kitty.

Yes, it's correct, but there is no need, I have pushed the correct fix, see my latest commit. 4878b7c

Thank you very much for your quick response, I really like kitty
