Characters for "...is slightly better" not working in Linux

Hi,

In my study rooms, when annotating, the characters for "white is slightly better" (unicode 2A72) and "black is slightly better" (unicode 2A71) do not seem to encode properly into Linux browsers. I am running Ubuntu 22.04, I have tested in Firefox and Chromium, both on their latest versions.

The encoding works fine in Windows 10 with Firefox. Problem seems Linux-specific. Anyone else had that problem?

Also the "white is much better", "black is much better", "white is winning", "black is winning" characters are all encoding fine, as well as all other annotation characters. The issue is limited to Unicode 2A71 and 2A72.

Thanks.
Your system doesn't have a font with Supplemental Mathematical Operators (2A00 - 2AFF range) support.
Install fonts-noto-core package, which will include Noto Sans Math that has these symbols.
Awesome that did the trick. Thank you very much @bufferunderrun I will take good note of this for future reference.
