- A variable-width character encoding capable of encoding all 1,112,064 valid code points in Unicode using one to four 8-bit bytes. The encoding is defined by the Unicode standard, and was originally designed by Ken Thompson and Rob Pike. The name is derived from “Unicode Transformation Format 8-Bit.” UTF-8 was designed for backward-compatibility with ASCII. UTF-8 is the dominant encoding for the World Wide Web (and Internet technologies), accounting for 98.2% of all web pages, 99.1% of the top 100,000 pages, and up to 100% for many languages, as of 2024. ← Wikipedia
