===== Unicode Transformation Format (UTF) =====
[[dido:public:ra:xapend:xapend.a_glossary:start| Return to Glossary ]]

The **Unicode Transformation Format (UTF)** is a character encoding format which is able to encode all of the possible character code points in Unicode. The most prolific is UTF-8, which is a variable-length encoding and uses 8-bit code units, designed for backwards compatibility with [[dido:public:ra:xapend:xapend.a_glossary:a:ascii|ASCII]] encoding.

Different kinds of UTF encodings include:

  * **UTF-1** — Retired predecessor of UTF-8, no longer part of the Unicode Standard
  * **UTF-7** — Uses 7 bits for encoding and was primarily used in email, but is now considered obsolete
  * **UTF-8** — Uses an 8-bit variable-width encoding in order to maximize compatibility with [[dido:public:ra:xapend:xapend.a_glossary:a:ascii|ASCII]]
  * **UTF-16** — [[dido:public:ra:xapend:xapend.a_glossary:00-9:16bit|16-bit]] variable-width encoding
  * **UTF-32** — [[dido:public:ra:xapend:xapend.a_glossary:00-9:32bit|32-bit]] fixed-width encoding
  * **UTF-EBCIDC** — Uses 8 bits and designed to be compatible with Extended Binary Coded Decimal Interchange Code (EBCDIC)
