  35         1 bit   mirrored property
  36         4 bits  directionality property
  37         9 bits  signed offset used for converting case
  38         1 bit   if 1, adding the signed offset converts the character to lowercase
  39         1 bit   if 1, subtracting the signed offset converts the character to uppercase
  40         1 bit   if 1, this character has a titlecase equivalent (possibly itself)
  41         3 bits  0  may not be part of an identifier
  42                 1  ignorable control; may continue a Unicode identifier or Java identifier
  43                 2  may continue a Java identifier but not a Unicode identifier (unused)
  44                 3  may continue a Unicode identifier or Java identifier
  45                 4  is a Java whitespace character
  46                 5  may start or continue a Java identifier;
  47                    may continue but not start a Unicode identifier (underscores)
  48                 6  may start or continue a Java identifier but not a Unicode identifier ($)
  49                 7  may start or continue a Unicode identifier or Java identifier
  50                 Thus:
  51                    5, 6, 7 may start a Java identifier
  52                    1, 2, 3, 5, 6, 7 may continue a Java identifier
  53                    7 may start a Unicode identifier
  54                    1, 3, 5, 7 may continue a Unicode identifier
  55                    1 is ignorable within an identifier
  56                    4 is Java whitespace
  57         2 bits  0  this character has no numeric property
  58                 1  adding the digit offset to the character code and then
  59                    masking with 0x1F will produce the desired numeric value
  60                 2  this character has a "strange" numeric value
  61                 3  a Java supradecimal digit: adding the digit offset to the
  62                    character code, then masking with 0x1F, then adding 10
  63                    will produce the desired numeric value
  64         5 bits  digit offset
  65         5 bits  character type
  66 
  67         The encoding of character properties is subject to change at any time.
