This character is a Other Symbol and is commonly used, that is, in no specific script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+273F forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
A fleuron (), also known as printers' flower, is a typographic element, or glyph, used either as a punctuation mark or as an ornament for typographic compositions. Fleurons are stylized forms of flowers or leaves; the term derives from the Old French: floron ("flower"). Robert Bringhurst in The Elements of Typographic Style calls the forms "horticultural dingbats". A commonly encountered fleuron is the ❦, the floral heart or hedera (ivy leaf). It is also known as an aldus leaf (after Italian Renaissance printer Aldus Manutius).
