Provides support for converting byte sequences to Strings and back again. The resulting Strings preserve the original byte sequences' sort order. The Strings are constructed using a Base 8000h encoding of the original binary data - each char of an encoded String represents a 15-bit chunk from the byte sequence. Base 8000h was chosen because it allows for all lower 15 bits of char to be used without restriction; the surrogate range [U+D8000-U+DFFF] does not represent valid chars, and would require complicated handling to avoid them and allow use of char's high bit. Although unset bits are used as padding in the final char, the original byte sequence could contain trailing bytes with no set bits (null bytes): padding is indistinguishable from valid information. To overcome this problem, a char is appended, indicating the number of encoded bytes in the final content char. This class's operations are defined over CharBuffers and ByteBuffers, to allow for wrapped arrays to be reused, reducing memory allocation costs for repeated operations. Note that this class calls array() and arrayOffset() on the CharBuffers and ByteBuffers it uses, so only wrapped arrays may be used. This class interprets the arrayOffset() and limit() values returned by its input buffers as beginning and end+1 positions on the wrapped array, resprectively; similarly, on the output buffer, arrayOffset() is the first position written to, and limit() is set to one past the final output array position.
