The Wikipedia has the following information about this codepoint:
The Illuy or Iluy (Hebrew: עִלּוּי) is a Trope (from Yiddish טראָפּ "trop") in the Judaic Liturgy. It is one of the cantillation marks used in the three poetic books: Job, the Book of Proverbs, and the Psalms. Accordingly, it is a special mark belonging to the Ta'amei Sifrei Emet (meaning, the accent signs of the books of truth).
