## 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 $\mathsf{Pr} \infty \mathsf{fWiki}$.
