This character is a Other Symbol and is commonly used, that is, in no specific script.

The Wikipedia has the following information about this codepoint:
Eris (; Greek: ἜριςÉris, "Strife") is the Greek goddess of strife and discord. Her Roman equivalent is Discordia, which means the same. Eris's Greek opposite is Harmonia, whose Roman counterpart is Concordia, though she is also described as opposing Nike, counterpart of the Roman Victoria. Homer equated her with the war-goddess Enyo, whose Roman counterpart is Bellona. The dwarf planet Eris is named after the goddess.
It is unknown whether she had any temples or sects in Greece. She is often invoked as a personification of strife, as which she appears in Homer and many later works.
