+ /* 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.
