Halfwidth Hangul Letter E

It is a halfwidth form of the Korean vowel ㅔ. Read it as the vowel sound /e/ when it stands alone. Unlike a vowel used to build a normal Korean syllable block, this spacing letter sits by itself; 에 is an example of a composed syllable.

The ordinary compatibility jamo ㅔ and the conjoining jamo ᅦ are related forms with different jobs. ￇ is the narrow, legacy-oriented form; it does not add a new vowel sound or word meaning.

Why does this halfwidth vowel exist?

It belongs to computer-era text standards. A near-identical set appears in the Xerox Character Code Standard trail associated with KS C 5601-1982. The closest documented source for Unicode’s arrangement is Annex 4 of KS C 5601/KS X 1001 from 1987 and later versions. This is a standards lineage, not a newly invented Korean letter.

Halfwidth forms gave individual Hangul letters a narrow cell for mixed-width text and helped preserve distinctions when data moved between encodings. The proposal says this exact set was not covered by a legacy character encoding and was already rare in practice. Use ordinary Korean input for Korean prose; this form is mainly for legacy data or testing.

Why did ￇ change after conversion?

Compatibility conversion can put it on the ordinary Hangul path. It can map ￇ through ㅔ to conjoining ᅦ. If neighboring jamo are also converted to conjoining forms, they may combine into a syllable. That is a change in text representation, not in meaning.

A missing box or unexpected width may be a font issue. A Unicode proposal reported weak coverage of halfwidth jamo in 2017.
