U209F

U+209F is a Unicode code point located in the Superscripts and Subscripts block. It is designated as a Latin subscript small letter and is intended for use in specialized typography that requires subscripted Latin letters. In practice, such characters appear in mathematical notation, phonetic transcriptions, and certain scientific or technical contexts that use subscripted letters beyond the common numeric subscripts.

As part of the Unicode standard, U+209F relies on font support for proper rendering. Many fonts do not include this specific glyph, so rendering may fall back to a similar-looking character or to a plain letter if the font lacks the character. With modern systems and fonts that cover the Superscripts and Subscripts range, the glyph is more reliably displayed when the appropriate font is installed.

Input and usage notes: U+209F can be entered through Unicode input methods, character maps, or by copying and pasting from sources that render the glyph. It is a standardized code point, but its appearance depends on the font in use and the conventions of the document or field in which it appears. In most everyday writing, this character is rarely required, but it is part of the broader set of typographic tools provided by Unicode for precise subscript notation.
