This character is a Lowercase Letter and is mainly used in the Georgian script. Its uppercase variant is Georgian Mtavruli Capital Letter En.
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+10D4 forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
Eni (asomtavruli Ⴄ, nuskhuri ⴄ, mkhedruli ე, mtavruli Ე) is the 5th letter of the three Georgian scripts.

Eni commonly represents the vowel /ɛ/, like the pronunciation of ⟨e⟩ in "embassy".
