• 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 dominant for all countries and languages on the Internet, with 99% global average use; it is used in most standards, often the only allowed encoding, and is supported by all modern operating systems and programming languages. ← Wikipedia
