Utf8 Appendable abstract base class
This abstract class wraps a standard Appendable
and provides methods to append UTF-8 encoded bytes, that are converted into characters.
This class is stateful and up to 4 calls to append(byte)
may be needed before state a character is appended to the string buffer.
The UTF-8 decoding is done by this class and no additional buffers or Readers are used. The UTF-8 code was inspired by
