a next beta will have

\definesymbol [bullet]        [\textormathchar{"2022}] % • \bullet
\definesymbol [dash]          [\textormathchar{"2013}] % –
\definesymbol [star]          [\textormathchar{"22C6}] % ✴ \star
\definesymbol [triangle]      [\textormathchar{"22B3}] % ⊳ \triangleright
\definesymbol [circle]        [\textormathchar{"2218}] % ∘ \circ
\definesymbol [square]        [\textormathchar{"25A1}] % □ \square
\definesymbol [diamond]       [\textormathchar{"22C4}] % ⋄ \diamond
\definesymbol [checkmark]     [\textormathchar{"2713}] % ✓ \checkmark

\definesymbol [blacktriangle] [\textormathchar{"25B6}] % ▶
\definesymbol [blacksquare]   [\textormathchar{"25A0}] % ■
\definesymbol [blackdiamond]  [\textormathchar{"25C6}] % ◆

but it's experimental (and fonts like cambria don't have all of them)
