0x21B

0x21B is a hexadecimal numeral that equals 539 in decimal. In programming and digital contexts, the prefix 0x indicates hexadecimal notation, so 0x21B can represent the constant value 539 in source code, or serve as an offset, identifier, or address in systems that use hex notation.

When interpreted as a Unicode code point, the sequence U+021B corresponds to the Latin small letter t with comma below (ț). Its uppercase counterpart is U+021A (Ț). These characters are part of the Latin Extended-B block and are used in Romanian orthography to represent the voiceless alveolar affricate /t͡s/. The letter ț appears in Romanian text and in some minority languages that employ similar Latin scripts.

In encoding and rendering, 0x21B is typically represented as the code point U+021B. In HTML and XML, it can be encoded with a numeric character reference such as ț (or ț in decimal) to produce ț. Because 0x21B exceeds the 8-bit range, it cannot be represented in 8-bit encodings like ISO-8859-1 without using a multibyte encoding such as UTF-8 or UTF-16.

Context matters for 0x21B: as a plain hex value it denotes 539, but in character encoding it often points to the Unicode code point U+021B for the latin small letter t with comma below.
