/* 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.
