Linguistic Note on Angstrom

The word angstrom is derived from a Swedish name, and properly has diacritics: ångström.

However, this "correct" presentation is tedious to implement and a nuisance to maintain, so $\mathsf{Pr} \infty \mathsf{fWiki}$ prefers the simple version angstrom.

Its symbol, however, does need the small circle above the A in order to be accurate and unambiguous.

This, unfortunately, is not straightforward to render in $\LaTeX$ without including further expansion sets.

Hence the $\LaTeX$ form as $\mathring {\mathrm A}$ (not a strictly accurate rendition) is how it is presented on $\mathsf{Pr} \infty \mathsf{fWiki}$.
