What ﾪ means
It is a narrow compatibility form of the Hangul cluster ㄺ.
A compatibility character preserves a form needed by older text systems. Modern Korean is normally written in syllable blocks, or with regular jamo when components are needed. This halfwidth jamo keeps older Korean character-set data in a narrow form; it does not add a new sound.
The documented trail is about computer character sets. The family follows Annex 4, the “7-bit hangul jamo character code,” in the 1987 and later revisions of the Korean KS C 5601/KS X 1001 standard. A near-identical Xerox character set points to the 1982 KS C 5601 standard. These dates describe the documented character-set trail, not a proven first appearance for this exact character.
During compatibility conversion, ﾪ can map toward ㄺ and then toward ᆰ, a conjoining trailing jamo used in Hangul processing.
How to type halfwidth Hangul?
For ordinary Korean writing, use a syllable block or regular Hangul jamo instead. Keep ﾪ when you need the exact narrow form for legacy text, a conversion test, or a round-trip requirement.
Why does halfwidth Hangul show as a box?
The font may lack a halfwidth glyph, or conversion may change the form.
A Unicode proposal reported in 2017 that most Korean fonts did not cover halfwidth jamo. Source Han Sans's 2025 readme says its halfwidth-jamo code points map to glyphs from the Hangul Compatibility Jamo block instead.
If you see ㄺ in place of ﾪ, the stored character may still be different: a font or conversion process can change the display or representation while preserving the Korean consonant cluster.
Technical and archival; ﾪ points to character-set compatibility rather than everyday Korean writing.
As of 2026, read a lone ﾪ as technical text or an accidental paste, not a reaction.

Questions people ask
2Is halfwidth Hangul used in Korean?
No. Modern Korean is normally written with syllable blocks and regular jamo. Halfwidth jamo remain for legacy character-set compatibility.
Can a font replace ﾪ with ㄺ?
Yes. Some fonts lack a dedicated halfwidth glyph or map the code point to a compatibility-jamo glyph. That changes the display, not necessarily the stored character.
