Canonicalize() public static method

Take a possibly escaped character literal and convert it to a canonical form. Thus @"'\377'", @"'\xff'" and @"'\u00FF'" all return @"'\xFF'". Throws a StringInterpretException if character ordinal exceeds "symLimit".
public static Canonicalize ( string source, int startIndex ) : string
source string
startIndex int start index of character
return string
