A buffer of chars.

A char buffer can be created in either one of the following ways:

• CharBuffer.Allocate(int) a new char array and create a buffer based on it;
• CharBuffer.Wrap(Char[]) an existing char array to create a new buffer;
• CharBuffer.Wrap(Java.Lang.ICharSequence) an existing char sequence to create a new buffer;
• Use ByteBuffer.AsCharBuffer to create a char buffer based on a byte buffer.
