The glyph is not a composition. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+0126 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:
Ħ (minuscule: ħ) is a letter of the Latin alphabet, derived from H with the addition of a bar. It is used in Maltese for a voiceless pharyngeal fricative consonant (corresponding to the letter heth of Semitic abjads: Arabic: ح, Hebrew: ח). Lowercase ħ is used in the International Phonetic Alphabet for the same sound. It was used for this sound in the 1556 work of Pérez de Ayala, slightly modified from Pedro de Alcalá's Vocabulary.
In Unicode, the special character ℏ (U+210F), represents the reduced Planck constant of quantum mechanics. In this context, it is pronounced "h-bar".
The lowercase resembles the Cyrillic letter Tshe (ћ), or the astronomical symbol of Saturn (♄).
A white uppercase Ħ on a red square was the logo of Heritage Malta until 2022.
It is used as the symbol for Hedera Hashgraph's native cryptocurrency, HBAR.
