302F

302F commonly refers to the Unicode code point U+302F, which has the character name IDEOGRAPHIC HALF FILL SPACE. It is located in the CJK Symbols and Punctuation block and is categorized as a space-like character used in East Asian typography.

The IDEOGRAPHIC HALF FILL SPACE is a whitespace character whose purpose is typographic rather than visible. It provides a narrow gap between ideographic characters and punctuation in some typesetting contexts, particularly in vertical writing or specialized layout schemes. Because it is a spacing character, it does not display as a visible glyph in most fonts, and its presence is often only detectable by its effect on line or column alignment rather than by any visible mark.

Encoding and usage: In Unicode, the code point is U+302F. In practical text processing, the character behaves as a spacing character, and many fonts do not render a distinct glyph for it. In UTF-16 it is represented by a single 16-bit unit, and in UTF-8 it is encoded as a three-byte sequence. Its use is relatively rare in everyday digital text today, but it is retained for compatibility with legacy East Asian typography and certain typesetting workflows.
