0x209F

0x209F is a hexadecimal notation that commonly refers to the Unicode code point U+209F. In Unicode, U+209F designates a character used for subscript forms of Latin letters, a capability that appears in some technical and phonetic contexts. The exact appearance of the character depends on font support; many standard fonts do not include this code point, so rendering may fall back to a placeholder glyph or a similar substitute.

Encoding and representation: In UTF-8, the code point U+209F is encoded as the three-byte sequence E2 82 9F. In environments that support Unicode, the character can also be represented with escape sequences, such as \u209F in languages that use 16-bit escapes, or as a numeric character reference in HTML: ₟ or ₟.

Usage and limitations: The use of U+209F is relatively specialized. It appears in contexts requiring precise subscript representation of Latin letters, such as certain scientific, mathematical, or typographic notations. Because font support for this code point is inconsistent, its availability can vary across platforms, applications, and browsers.

Related code points: The Latin subscript letter range includes several nearby characters used for subscripts in Latin typography, and related subscript digits appear in the 0x2080–0x2089 range. In Unicode terms, rendering of these characters is contingent on the chosen font and rendering engine.
