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.

<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.

AD 8 was a leap year starting on Sunday (link will display the full calendar) of the Julian calendar. In the Roman Empire, it was known as the Year of the Consulship of Camillus and Quinctilianus (or, less frequently, 761 Ab urbe condita).

UTF-32 (32-bit Unicode Transformation Format) is a fixed-length encoding used to encode Unicode code points that uses exactly 32 bits (four bytes) per code point (but a number of leading bits must be zero as there are far fewer than 232 Unicode code points, needing actually only 21 bits). UTF-32 is a fixed-length encoding, in contrast to all other Unicode transformation formats, which are variable-length encodings.

The Bundesstraße 8 (abbr. B8) is a German federal highway in southwestern Germany of great historical importance.

The Hongdu JL-8 (Nanchang JL-8), also known as the Karakorum-8 or K-8 for short, is a two-seat intermediate jet trainer and a light attack aircraft designed in the People's Republic of China by China Nanchang Aircraft Manufacturing Corporation. The primary contractor is the Hongdu Aviation Industry Corporation.

UTF-EBCDIC is a character encoding capable of encoding all 1,112,064 valid character code points in Unicode using one to five one-byte (8-bit) code units (in contrast to a maximum of four for UTF-8). It is meant to be EBCDIC-friendly, so that legacy EBCDIC applications on mainframes may process the characters without much difficulty.
