From The Free On-line Dictionary of Computing (30 December 2018) :

     1.  A 16-bit character set standard, designed and
     maintained by the non-profit consortium Unicode Inc.
     Originally Unicode was designed to be universal, unique, and
     uniform, i.e., the code was to cover all major modern written
     languages (universal), each character was to have exactly one
     encoding (unique), and each character was to be represented by
     a fixed width in bits (uniform).
     ISO/{IEC">Parallel to the development of Unicode an ISO/{IEC
     standard was being worked on that put a large emphasis on
     being compatible with existing character codes such as ASCII
     or ISO Latin 1.  To avoid having two competing 16-bit
     standards, in 1992 the two teams compromised to define a
     common character code standard, known both as Unicode and
     Since the merger the character codes are the same but the two
     standards are not identical.  The ISO/IEC standard covers only
     coding while Unicode includes additional specifications that
     help implementation.
     Unicode is not a glyph encoding.  The same character can be
     displayed as a variety of glyphs, depending not only on the
     font and style, but also on the adjacent characters.  A
     sequence of characters can be displayed as a single glyph or a
     character can be displayed as a sequence of glyphs.  Which
     will be the case, is often font dependent.
