| /* 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. |
