Comment 3 for bug 1811538

Ah that's interesting. I found the bug report where gnome-weather changed to use the single-codepoint encoding (https://bugzilla.gnome.org/show_bug.cgi?id=785274), and this is what made me think it was the preferred encoding. They were concerned about linebreaks between the ° and the C/F, not about looking good in monospaced fonts as I had guessed.

But if these are compatibility characters then I will report the bug against gnome-weather suggesting not to use them.

Will leave this one open though since they're still missing characters.
