CJK Stroke Sg

It marks a vertical stroke that ends in a hook. The Chinese stroke name is 竖钩 (traditional 豎鉤), literally “vertical hook”: 竖/豎 means upright, and 钩/鉤 means hook. Unicode examples show it as the first stroke in 水 (“water”) and as part of 爭, 事, and 求.

The stroke existed in writing before its digital encoding. Sixteen stroke entries derived from Hong Kong’s Supplementary Character Set entered Unicode 4.1; a proposal in 2006 added 20 more types, including SG, for indexing and sorting. Unicode 5.1 (2008) dates the encoding, not the invention of the stroke.

Why was ㇚ encoded?

It gives reference systems a label for one specific stroke. Unicode groups it with CJK (Chinese, Japanese, and Korean) stroke components, used mainly to index written characters or sort them in reference systems. These components stay distinct from single-stroke characters and radicals, even when their outlines look similar.

An ideographic description sequence (IDS) is notation for showing how a Han character is built. Unicode’s IDS grammar allows a CJK Stroke such as ㇚ as one of its pieces.

What does ㇚ mean when someone sends it?

Treat a lone ㇚ as technical notation about a stroke. Its standard role points to stroke structure, an index, or a discussion about text rendering or input. Read any more personal meaning from the surrounding message, not from this mark alone.
