  • defines a set of graphic characters used in scripts and the written form of languages on a world-wide scale;
  • specifies the names for the graphic characters and format characters of the BMP, SMP, SIP, TIP, SSP and their coded representations within the UCS codespace;
  • specifies the coded representations for control characters and private use characters;
