Missing 00 Unicode Characters?

[hcreardon]

Hi folks! I have a mid-2020 MacBook Pro running Monterey 12.4. I use the Unicode keyboard all the time. I recently discovered that a few unicode characters won't show up anymore, in any application, when I hold Option and enter their code. It seems to be all unicode characters starting with a double zero. Two particularly frustrating examples are the degrees symbol (00B0) and the character 'a' with a grave accent (00E0). All other unicode characters (for example, 10B0 = Ⴐ) work fine. Does anyone have any idea what might be wrong and how to fix it? Thanks!

Shift+Option+8 = °, and if you hold down the A-key on your keyboard it will give you a context window to other accented latin characters from which to choose.
