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+2720 forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
A cross pattée, cross patty or Pate, or cross paty, also known as a cross formy or cross formée (French: croix pattée, German: Tatzenkreuz) or Templar cross, is a type of Christian cross with arms that are narrow at the centre, and often flared in a curve or straight line shape, to be broader at the perimeter. The form appears very early in medieval art, for example in a metalwork treasure binding given to Monza Cathedral by Lombard queen Theodelinda (died 628), and the 8th-century lower cover of the Lindau Gospels in the Morgan Library. An early English example from the start of the age of heraldry proper (i.e. about 1200) is found in the arms of Baron Berkeley.
