Usage notes
As either a gender or chemical symbol, this character should display as a simple circle rather than as an emoji. Appending the variation selector &amp;#xFE0E; will override emoji formatting. Technically, for 'oxygen' the font color should be set to red, $⟨⚪| ⚪&#xFE0E;⟩$, though it's not uncommon for that detail to be omitted. The old chemical symbol might instead by typeset with the full-moon character $⟨🌕&#xFE0E;⟩$, depending on which better matches the size of other element symbols.
