Halfwidth Hangul letter rieul-phieuph

175/225

ᆵ is the halfwidth form of the Korean jamo cluster ㄿ, made from rieul (ㄹ) and phieuph (ㅍ). It belongs to legacy Korean encoding data; ordinary modern Korean uses ㄿ or a syllable containing it. Its story is about computer standards and character conversion.

Text symbol

What ᆵ means

It represents the Korean jamo cluster ㄿ. Jamo are the building blocks of Hangul, the Korean writing system. The cluster joins rieul (ㄹ) and phieuph (ㅍ), as in the Korean verbs 읊다 and 읊조리다; ᆵ itself is not the usual spelling of either word.

The history of halfwidth Hangul jamo belongs to computer standards. The earliest KS C 5601 edition, published in 1974, defined a variable-length 7-bit N-byte Hangul set. A Unicode proposal linked the UFFxx arrangement to the 1987-era KS C 5601 / KS X 1001 Annex 4.

Halfwidth Hangul was intended to let older Korean encodings round-trip individual jamo through mixed-width systems. This character is now a Unicode compatibility form for legacy data; modern Hangul is normally arranged in syllable blocks.

Why does ᆵ look broken?

Some fonts may omit it, or it may sit alone instead of joining a syllable. Halfwidth jamo are compatibility forms, not required to write Korean. In 2017, a Unicode proposal reported that Korean input methods did not offer them and many Korean fonts did not cover them. A missing-glyph box or a display as ㄿ reflects software support, not a new reading.

Compatibility normalization maps ᆵ to ㄿ, and Korean-specific text processing can combine jamo into a syllable-shaped block. If the original character matters, check whether normalization has changed it.

Technical and archival, rather than conversational; without context, it can look like leftover encoding data.

For ordinary Korean writing, use ㄿ or a syllable containing it.

Questions people ask

2

Is ᆵ suitable for ordinary Korean messages?

Usually no. It is a legacy halfwidth form that may not display or enter reliably; use ㄿ or a Korean syllable containing the cluster for ordinary text.

Can text processing change ᆵ?

Yes. Compatibility normalization can map it to ㄿ, so the original and normalized strings may differ.
