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+0804 forms with similar adjacent characters prevents a line break inside it.
