Character (GWT 2.8.2)

java.lang.Object
- java.lang.Character

All Implemented Interfaces:: Serializable, Comparable<Character>

public final class Character
extends Object
implements Comparable<Character>, Serializable

Wraps a native char as an object. TODO(jat): many of the classification methods implemented here are not correct in that they only handle ASCII characters, and many other methods are not currently implemented. I think the proper approach is to introduce * a deferred binding parameter which substitutes an implementation using a fully-correct Unicode character database, at the expense of additional data being downloaded. That way developers that need the functionality can get it without those who don't need it paying for it.

 The following methods are still not implemented -- most would require Unicode
 character db to be useful:
  - digit / is* / to*(int codePoint)
  - isDefined(char)
  - isIdentifierIgnorable(char)
  - isJavaIdentifierPart(char)
  - isJavaIdentifierStart(char)
  - isJavaLetter(char) -- deprecated, so probably not
  - isJavaLetterOrDigit(char) -- deprecated, so probably not
  - isISOControl(char)
  - isMirrored(char)
  - isSpaceChar(char)
  - isTitleCase(char)
  - isUnicodeIdentifierPart(char)
  - isUnicodeIdentifierStart(char)
  - getDirectionality(*)
  - getNumericValue(*)
  - getType(*)
  - reverseBytes(char) -- any use for this at all in the browser?
  - toTitleCase(*)
  - all the category constants for classification

 The following do not properly handle characters outside of ASCII:
  - digit(char c, int radix)
  - isDigit(char c)
  - isLetter(char c)
  - isLetterOrDigit(char c)
  - isLowerCase(char c)
  - isUpperCase(char c)
