When to use it

&nvltrie; writes a sequence of 2 code points (U+22B4 U+20D2) that together show as one symbol. Specialist notation like this usually belongs in MathML, which positions it correctly; the entity is for occasional use in running text.

The name comes from the HTML5 list (much of it shared with MathML), so it works in every current browser but not in XML or XHTML served as XML, where the numeric reference is the safe choice.
