IsDecimalDigitChar ( int c ) : bool	Returns true for unicode characters of class Nd.
IsDigit ( char c ) : bool	Returns true if the character is a valid decimal digit for numeric literals.
IsDigitInRadix ( char c, int radix ) : bool	Returns true if the character is a valid digit for numeric literals in the given radix.
IsFormattingChar ( int c ) : bool	Returns true for unicode characters of class Cf.
IsIdentifierPart ( int c ) : bool	Returns true if the unicode character is an identifier start or a combining, decimal digit, connecting, or formatting char.
IsIdentifierStart ( int c ) : bool	Returns true if the unicode character is a letter char or an underscore (U+005F).
IsKw ( string s ) : bool	Returns true if the given image is a keyword.
IsLetterChar ( int c ) : bool	Returns true for unicode characters of classes Lu, Ll, Lt, Lm, Lo, or Nl.
IsNumPrefix ( char c ) : bool	Returns true if the character is valid for a number prefix, false otherwise.
