class RichChar
[source: scala/runtime/RichChar.scala]
final class RichChar(x : Char)
extends Proxy with Ordered[Char]

For example, in the following code 

    object test extends Application {
      Console.println('\40'.isWhitespace)
      Console.println('\011'.isWhitespace)
      Console.println('1'.asDigit == 1)
      Console.println('A'.asDigit == 10)
    }

the implicit conversions are performed using the predefined view Predef.charWrapper.

Method Summary
def asDigit : Int
def compare (y : Char) : Int
Result of comparing this with operand that. returns x where x < 0 iff this < that x == 0 iff this == that x > 0 iff this > that
def isControl : Boolean
def isDigit : Boolean
def isLetter : Boolean
def isLetterOrDigit : Boolean
def isLowerCase : Boolean
def isUpperCase : Boolean
def isWhitespace : Boolean
def self : Any
def to (y : Char) : Projection[Char]
Create a RandomAccessSeq.Projection[Char] over the characters from 'x' to 'y'
def toLowerCase : Char
def toUpperCase : Char
def until (limit : Char) : Projection[Char]
Create a RandomAccessSeq.Projection[Char] over the characters from 'x' to 'y' - 1
