    /* The character properties are currently encoded into 32 bits in the following manner:
        1 bit   mirrored property
        4 bits  directionality property
        9 bits  signed offset used for converting case
        1 bit   if 1, adding the signed offset converts the character to lowercase
        1 bit   if 1, subtracting the signed offset converts the character to uppercase
        1 bit   if 1, this character has a titlecase equivalent (possibly itself)
        3 bits  0  may not be part of an identifier
                1  ignorable control; may continue a Unicode identifier or Java identifier
                2  may continue a Java identifier but not a Unicode identifier (unused)
                3  may continue a Unicode identifier or Java identifier
                4  is a Java whitespace character
                5  may start or continue a Java identifier;
                   may continue but not start a Unicode identifier (underscores)
                6  may start or continue a Java identifier but not a Unicode identifier ($)
                7  may start or continue a Unicode identifier or Java identifier
                Thus:
                   5, 6, 7 may start a Java identifier
                   1, 2, 3, 5, 6, 7 may continue a Java identifier
                   7 may start a Unicode identifier
                   1, 3, 5, 7 may continue a Unicode identifier
                   1 is ignorable within an identifier
                   4 is Java whitespace
        2 bits  0  this character has no numeric property
                1  adding the digit offset to the character code and then
                   masking with 0x1F will produce the desired numeric value
                2  this character has a "strange" numeric value
                3  a Java supradecimal digit: adding the digit offset to the
                   character code, then masking with 0x1F, then adding 10
                   will produce the desired numeric value
        5 bits  digit offset
        5 bits  character type

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