UTF-8

UTF-8 is a technical specification rather than a natural language word, functioning as the industry standard for character encoding on the web. It is used to ensure that text is rendered consistently across different operating systems and browsers, regardless of the language or script being used.

As a technical term referring to a specific protocol, it is treated as an uncountable noun. It does not have a plural form and is typically used without an article when referring to the encoding standard itself (e.g., "encoded in UTF-8").
