Fonts don't render

@richard based on the blog comments, I guess it's not only me.

Oh, and I ran into this in a fresh bundle, as well, after some browsing. I'll try to get S.T.R.

This may be a red herring, but www.torproject.org/zh-CN does not render Noto Sans SC Regular. It seems like there's something wrong with our bundled fonts. If you unset FONTCONFIG*, and use system fonts, then it renders correctly.

I tried bundling NotoSansCJKsc-Regular and now that page renders.

I wonder if we should pick up a newer version of noto fonts.

I hear this is not a problem on all Linux64 systems, exciting.

Minimal example: https://people.torproject.org/~sysrqb/testing/font_zh-CN.html

tl;dr it seems like the cmap isn't being initialized correctly when restricted to bundled fonts. I don't know why we're seeing inconsistent behavior on different linux64 systems, though.

Font logs only using bundled fonts:

compared with font logs when not restricting fonts, notice it's using the bundled font:

If I move all of the fonts out of fonts/ except for NotoSansSC-Regular.otf, then the font is correctly chosen and the characters render correctly.

for me it's like this:

A user on frontdesk has reported:

I downloaded and installed Tor 11.0 on Fedora 35.

Open a terminal and cd to the tor-browser_en-US directory.

Start the browser via ./start-tor-browser.desktop

$ ./start-tor-browser.desktop --verbose Launching './Browser/start-tor-browser --detach --verbose'... Fontconfig warning: "~~/bin/tor-browser_en-US/Browser/TorBrowser/Data/fontconfig/fonts.conf", line 37: Use of ambiguous path in element. please add prefix="cwd" if current behavior is desired. Fontconfig warning: "~~/bin/tor-browser_en-US/Browser/TorBrowser/Data/fontconfig/fonts.conf", line 85: unknown element "blank"

The browser can not locate the fonts and displays the browser chrome font as unicode "boxes".

Changing the Font directory list to <dir prefix="relative">fonts</dir> fixes the issue for me.

Not sure what the issue is with the message about blank.

Thanks!

This should be fixed in the 11.0.1.

@sysrqb the change you made in !366 (closed) doesn't work for me.

Only prefix="relative" fixes the issue!

If 'prefix' is 'default' or 'cwd', then the current working directory will be added prior to the value.

If 'prefix' is 'xdg', then the value in the $XDG_DATA_HOME will be added prior to the value.

If 'prefix' is 'relative', then the path of curent file will be added prior to the value.

I was able to reproduce the issue in a fedora-33 VM.

Adding prefix="cwd" is removing the warning, however it is not fixing the issue. But replacing fonts with an invalid path is fixing the issue. Which is probably why using prefix="relative" is fixing it too (fonts is an invalid path relative to fonts.conf directory).

So it seems the issue is with something in the fonts directory.

Ah, indeed, I misread the fix mentioned in #40382 (comment 2760098).

<dir prefix="relative">fonts</dir>

didn't work for me

is crazy

(Ubuntu 18.04.6 LTS, 64-bit -- used "updater" notification)

I'm just a barely tech-y casual user; how do I fix this? Thanks.

marked this issue as related to tor-browser#40703 (moved)

It doesn't look THAT bad for me, but I noticed that some websites now seem to be rendered using different fonts than they used to be rendered with ... and typically the new fonts look somewhat off (e.g., too small or not aesthetically pleasing ...). I'll update this once I come across specific examples.

I notice that the font in this text entry box here doesn't look great (but it's OK once I click "Preview"), but I don't remember exactly what it used to look like.

mentioned in issue tor-browser#40690 (closed)

Any solutions yet? ...or an 11.0.1 update?

Edit: 11.0.1 seems kick butt so far! Thanks so much for what you do. Maybe there was some error in releasing the previous update as though it were a stable update? It looked to me like that was the intention, and I unwittingly plunged into some out of my league troubleshooting. On Ubuntu 18, it's working well now.

Concerns persist. Fedora 35

GitHub Gists are an example where fonts suddenly look different ... and not nice I think. This is with 11.0.1.
