<h4>Greek</h4>

  alphabet, written left-to-right (11 million users). Used to write the Greek

  distinct letters for consonants and vowels. Standardized in the 4th century
  BCE by Eucleides. Has 24 letters. Some letter variants (sigma: σ/ς) have
  positional significance in the Greek language, other variants only differ in
  meaning in scientific notation (e.g. pi: π/ϖ). The Greek language used to be
  written in polytonic spelling, with three accents on vowels. In 1982, Greece
  introduced monotonic spelling with a single diacritic. Needs software support
  for complex text layout (shaping). Read more on
