I just not sure why they put in the "Angstrom symbol" to begin with. If you do, then why isn't the "meter symbol" (m) also represented?
Fortunately, it seems like it's marked as deprecated: https://en.wikipedia.org/wiki/Angstrom#Symbol

Frequently, the answer to this is "some obscure character set had this as a distinct symbol." In this case, blame the Japanese: https://en.wikipedia.org/wiki/JIS_X_0208
Which is why there's an 'mm' and 'cm' and other random symbols: https://www.compart.com/en/unicode/block/U+3300
