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+03D7 forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.
El Wikipedia tiene la siguiente información acerca de este punto de código:
Kai (και "and"; Modern Greek:[ce]; Ancient Greek:[kai]; sometimes abbreviated k) is a word that is a conjunction in Greek, Coptic (ⲕⲁⲓ) and Esperanto (kaj; IPA:[kai̯]).
Kai is the most frequent word in any Greek text and thus used by statisticians to assess authorship of ancient manuscripts based on the number of times it is used.
