The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+AB53 forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.
The Wikipedia has the following information about this codepoint:
Chi (KY, also KHEE; uppercase Χ, lowercase χ; Greek: χῖ) is the twenty-second letter of the Greek alphabet.
