UTF-8 is a variable-width character encoding used for electronic communication. Defined by the Unicode Standard, the name is derived from Unicode (or Universal Coded Character Set) Transformation Format 8-bit.

UTF-8

ASCII-COMPATIBLE VARIABLE-WIDTH ENCODING OF UNICODE, USING ONE TO FOUR BYTES

<character> (UCS transformation format 8) An ASCII-compatible multibyte Unicode and UCS encoding, used by Java and Plan 9. The Unicode character set occupies a 16-bit code space. The most obvious Unicode encoding (known as UCS-2) consists of a sequence of 16-bit words. Such strings can contain bytes like '' or '/' which have a special meaning in filenames and other C library function parameters. In addition, the majority of Unix tools expects ASCII files and can't read 16-bit words as characters without major modifications. For these reasons, UCS-2 is not a suitable external encoding of Unicode in filenames, text files, environment variables, etc. The ISO 10646 Universal Character Set (UCS), a superset of Unicode, occupies a 31-bit code space and the obvious UCS-4 encoding for it (a sequence of 32-bit words) has the same problems. The UTF-8 encoding of Unicode and UCS avoids the problems of fixed-length Unicode encodings because an ASCII file encoded in UTF is exactly same as the original ASCII file and all non-ASCII characters are guaranteed to have the most significant bit set (bit 0x80). This means that normal tools for text searching etc. work as expected. UTF-8 is defined in RFC 2279.

CESU-8

ENCODING SCHEME FOR UNICODE, SIMILAR TO UTF-8 EXCEPT THAT NON-BMP CHARACTERS ARE ENCODED FIRST AS A PAIR OF UTF-16 SURROGATES, THEN UTF-8-ENCODED; DISCOURAGED FOR USE EXCEPT INTERNALLY FOR COMPATIBILITY REASONS

CsCESU8; CsCESU-8; Compatibility Encoding Scheme for UTF-16; Compatibility Encoding Scheme for UTF-16: 8-Bit

The Compatibility Encoding Scheme for UTF-16: 8-Bit (CESU-8) is a variant of UTF-8 that is described in Unicode Technical Report #26. A Unicode code point from the Basic Multilingual Plane (BMP), i.
