Variance indicators

  • With Unicode 3.1.1, a new mechanism for encoding glyph variants has been introduced
  • Some `variance indicators' have been assigned, currently only for Mongolian
  • The idea behind this mechanism is as follows:
    • a variance indicator is used in adjunction with a character codepoint
    • it indicates that a different glyph should/could be used to render it
    • the glyph to use is taken from tables of glyph variants maintained by the Unicode Consortium
  • The entry barriers to this mechanism are similar as for new characters.
  • The Unicode consortium does not want to see this used for i.e. encoding of variant glyphs in manuscripts or similar purposes
