  17.     /* The character properties are currently encoded into 32 bits in the following manner:

  18.         1 bit   mirrored property

  19.         4 bits  directionality property

  20.         9 bits  signed offset used for converting case

  21.         1 bit   if 1, adding the signed offset converts the character to lowercase

  22.         1 bit   if 1, subtracting the signed offset converts the character to uppercase

  23.         1 bit   if 1, this character has a titlecase equivalent (possibly itself)

  24.         3 bits  0  may not be part of an identifier

  25.                 1  ignorable control; may continue a Unicode identifier or Java identifier

  26.                 2  may continue a Java identifier but not a Unicode identifier (unused)

  27.                 3  may continue a Unicode identifier or Java identifier

  28.                 4  is a Java whitespace character

  29.                 5  may start or continue a Java identifier;

  30.                    may continue but not start a Unicode identifier (underscores)

  31.                 6  may start or continue a Java identifier but not a Unicode identifier ($)

  32.                 7  may start or continue a Unicode identifier or Java identifier

  33.                 Thus:

  34.                    5, 6, 7 may start a Java identifier

  35.                    1, 2, 3, 5, 6, 7 may continue a Java identifier

  36.                    7 may start a Unicode identifier

  37.                    1, 3, 5, 7 may continue a Unicode identifier

  38.                    1 is ignorable within an identifier

  39.                    4 is Java whitespace

  40.         2 bits  0  this character has no numeric property

  41.                 1  adding the digit offset to the character code and then

  42.                    masking with 0x1F will produce the desired numeric value

  43.                 2  this character has a "strange" numeric value

  44.                 3  a Java supradecimal digit: adding the digit offset to the

  45.                    character code, then masking with 0x1F, then adding 10

  46.                    will produce the desired numeric value

  47.         5 bits  digit offset

  48.         5 bits  character type

  49. 

  50.         The encoding of character properties is subject to change at any time.
