This character is a Other Letter and is mainly used in the Ogham script.
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+168D forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
nGéadal (Ngéadal or Ngeadal) is the Irish name of the thirteenth letter of the Ogham alphabet, ᚍ.
The Bríatharogam (kennings) for the letter are:
lúth lego "sustenance of a leech"
étiud midach "raiment of physicians"
tosach n-échto "beginning of slaying"
Its meaning is probably "[the act of] wounding". In Old Irish, the letter name was Gétal. It may be a verbal noun of gonid 'wounds, slays'. in which case is related to Welsh gwanu 'to pierce, to stab', which comes from the root was *gʷhen- 'to pierce, to strike'. Its original phonetic value in Primitive Irish was [ɡʷ], the voiced labiovelar. In Old Irish, this phoneme merged with g (gort), and the medieval manuscript tradition assigns it Latin ng[ŋ], hence the unetymological spelling of the letter name with initial n-.
