What ᅭ means
It is a narrow form of the Korean vowel ㅛ (yo). A jamo is a Korean letter used alone or combined with other letters to form a syllable; this character keeps the same vowel reading but has a compatibility width.
The source trail described in a 2017 Unicode proposal includes KS C 5601-1982 and a 7-bit Hangul-jamo annex associated with KS C 5601 / KS X 1001 from 1987. It also notes a nearly identical set in the Xerox Character Code Standard, while treating the trail as likely rather than settled. These forms served older computer text interchange and fixed-width display, where characters could occupy one or two cells.
Should I use ᅭ instead of ㅛ?
Use ㅛ in ordinary Korean; keep ᅭ for compatibility work.
The forms connect in different ways: ᅭ has a compatibility mapping to ㅛ, while ᅭ is the conjoining vowel used in letter sequences that can form syllables. They share the vowel reading but have different encoding roles. The change across older systems and Unicode is in representation, not the vowel.
Technical and legacy; it belongs to encoding or width work rather than ordinary Korean tone.
Some Korean fonts lack halfwidth jamo, so ᅭ may not display even when the text contains it.

Questions people ask
1Will NFKC change ᅭ?
Yes. NFKC and NFKD can map ᅭ to ㅛ, removing the halfwidth distinction. Use those normalizations only when that distinction can be lost.
