A variable-width encoding is a type of character encoding scheme in which codes of differing lengths are used to encode a character set (a repertoire of symbols) for representation, usually in a computer. Most common variable-width encodings are multibyte encodings, which use varying numbers of bytes to
UTF-8 is a variable-length character encoding standard used for electronic communication. Defined by the Unicode Standard, the name is derived from Unicode Transformation Format – 8-bit. [1] UTF-8 is capable of encoding all 1,112,064 [a] valid Unicode code points using one to four one- byte (8-bit) code units.
A variable-length quantity (VLQ) was defined for use in the standard MIDI file format to save additional space for a resource-constrained system, and is also used in the later Extensible Music Format (XMF). Base-128 is also used in ASN.1 BER encoding to encode tag numbers and object identifiers.
