ForDigit ( int digit, int radix ) : char
GetType ( int codePoint ) : UnicodeCategory	LUCENENET safe way to get unicode category. The .NET char.ConvertFromUtf32(int) method should be used first to be safe for surrogate pairs. However, if the value falls between 0x00d800 and 0x00dfff, that method throws an exception. So this is a wrapper that converts the codepoint to a char in those cases. This mimics the behavior of the Java Character.GetType class, but returns the .NET UnicodeCategory enumeration for easy consumption.
