U202F

U+202F, commonly named Narrow No-Break Space (NNBSP), is a whitespace character in the Unicode character set. It belongs to the general category Space Separator (Zs) and is designed to render as a narrow space that does not permit a line break at its position. It is distinct from the regular space (U+0020) and the standard non-breaking space (U+00A0) in both width and typographic behavior.

The visual width of U+202F is font-dependent, typically close to a quarter of an em, making it narrower than U+00A0 but wider than a hair or thin space in some fonts. As a no-break space, text may not wrap at U+202F, which helps keep adjacent elements together in justification or tight layouts. Rendering can vary across fonts and software, so its appearance is not guaranteed to be uniform.

Usage of U+202F is primarily in typographic contexts requiring compact, non-breaking spacing. It can be useful between numbers and units, in languages that prefer tighter interword spacing, or in justified text where a narrower non-breaking gap is desirable. Its usage is less common in everyday plain text, where U+2009 (thin space) or U+00A0 (non-breaking space) are more frequently employed, but it remains supported by modern fonts and rendering engines.

Encoding and representation: U+202F is a Unicode scalar value and is encoded in UTF-8 as a three-byte sequence. In HTML or XML, it can be represented as   or  . In many programming languages, it can be escaped as \u202F. See also non-breaking space and related spacing characters.
