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+0544 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:
The Armenian alphabet (Armenian: Հայոց գրեր, Hayocʼ grer or Հայոց այբուբեն, Hayocʼ aybuben) or, more broadly, the Armenian script, is an alphabetic writing system developed for Armenian and occasionally used to write other languages. It was developed around 405 CE by Mesrop Mashtots, an Armenian linguist and ecclesiastical leader. The script originally had 36 letters. Eventually, two more were adopted in the 13th century. In reformed Armenian orthography (1920s), the ligature ևev is also treated as a letter, bringing the total number of letters to 39.
The Armenian word for 'alphabet' is այբուբեն (aybuben), named after the first two letters of the Armenian alphabet: ⟨Ա⟩ Armenian: այբayb and ⟨Բ⟩ Armenian: բենben. Armenian is written horizontally, left to right.
