Strong, weak and neutral bidirectional character classes. The backing value of each case is the class abbreviation used as key of Type::STRONG, Type::WEAK and Type::NEUTRAL. The explicit formatting codes (LRE, LRO, RLE, RLO, PDF, LRI, RLI, FSI, PDI) are not part of this set.

Cases

  • L = 'L'
  • R = 'R'
  • AL = 'AL'
  • EN = 'EN'
  • ES = 'ES'
  • ET = 'ET'
  • AN = 'AN'
  • CS = 'CS'
  • NSM = 'NSM'
  • BN = 'BN'
  • B = 'B'
  • S = 'S'
  • WS = 'WS'
  • ON = 'ON'
