x202F

x202F refers to the Unicode code point U+202F, named Narrow No-Break Space (NNBS). It is a whitespace character classified as a non-breaking space, but with a narrower visual width than the standard non-breaking space (U+00A0). As part of the Unicode space separator set, it is intended for typographic use where a non-breaking constraint is required without consuming the full width of a regular space.

The primary purpose of the Narrow No-Break Space is to prevent line breaks at its position while taking up relatively little horizontal space. Typical use cases include keeping numbers and units together (for example, "25 kg") or formatting in narrow text layouts where space efficiency matters. The exact appearance depends on the font and rendering system, so its width can vary between environments.

In digital text processing, U+202F is generally treated as a non-breaking whitespace character. It can be preserved by Unicode-compliant software, but behavior may vary in editors, converters, or web content depending on font rendering and layout rules. When displayed or copied, the character may be indistinguishable from other compact spaces in some fonts, while in others it remains visibly narrower than U+00A0.

Related characters include U+00A0 NO-BREAK SPACE, U+2009 THIN SPACE, and U+200A HAIR SPACE. The narrow no-break space is part of Unicode’s broader set of spacing and non-spacing characters used to fine-tune typography and text wrapping.
