Halfwidth Hangul Rieul-Sios

It is a Hangul consonant cluster in a spacing compatibility form. The cluster is called rieul-sios. This character stands alone; it does not combine with neighboring jamo to build a syllable block.

If it appears by itself in a message, read it as a technical text character. The glyph has no established standalone word or conversational meaning.

Why was ﾭ made?

It preserves a width distinction in older Korean text. Halfwidth characters were used in mixed-width computing, where narrow and fullwidth cells had to retain their forms during conversion. This character belongs to that compatibility system, rather than to a separate Korean spelling convention.

A Unicode proposal from 2017 traces the halfwidth jamo repertoire to older Korean character-code references. Its trail includes a Xerox Character Code Standard reference to KS C 5601-1982 and Annex 4 of KS C 5601/KS X 1001 in the 1987 and later versions. This trail does not establish a first use or a single inventor.

Why is ﾭ hard to type or display?

Many Korean keyboards do not offer halfwidth jamo, and some fonts lack them. If ﾭ appears as a box or fallback symbol, the font may not support it.

Compatibility normalization maps ﾭ to ㄽ, removing the halfwidth distinction. The character is a spacing form, so putting it beside a vowel will not make a normal Hangul syllable block. Use ordinary Hangul jamo or a complete syllable for Korean writing.
