This character is a Other Letter and is mainly used in the Samaritan script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written from right to left. When changing direction it is not mirrored. The word that U+0809 forms with similar adjacent characters prevents a line break inside it.
El Wikipedia tiene la siguiente información acerca de este punto de código:
La yod (𐤉) es la décima letra del alfabeto fenicio. Representaba el sonido palatal sonoro y fricativo transliterado como /j/.[1] De esta letra derivan la yud siríaca (ܝ), la yod hebrea (י), la yāʾ árabe (ي), la iota (Ι) griega, las I y J latinas y las І, Ї y Ј cirílicas.
Debido a la pronunciación semivocálica de esta letra, da su nombre al fenómeno lingüístico yod.
