zhHant

zhHant is an IETF language tag used to designate the Traditional Chinese script within the Chinese language family. It is not a distinct language, but a script variant of Chinese. The tag is used in software localization, web content, and data interchange to indicate that text is written in Traditional Chinese characters rather than Simplified Chinese (zh-Hans). In practice, zh-Hant is typically written as zh-Hant, with some contexts permitting a variant without the dash (zhHant).

Traditional Chinese characters are used in Taiwan, Hong Kong, Macau, and many overseas Chinese communities. The tag can be combined with region subtags to reflect locale-specific conventions, such as zh-Hant-TW for Taiwan, zh-Hant-HK for Hong Kong, and zh-Hant-MO for Macau.

Standards and encoding: In ISO 15924, the script code for Traditional Chinese is Hant, contrasted with Hans for Simplified Chinese. In BCP 47, zh is the language code for Chinese and Hant is the script subtag. The combination enables precise tagging of content and data interchange across systems that support multiple Chinese scripts.

Notes: zh-Hant denotes the script variant rather than a separate language, and regional orthographic conventions can vary within Traditional Chinese contexts. Unicode encodes the full set of Traditional Chinese characters, supporting accurate rendering and interchange of zh-Hant content across platforms.
