org.eclipse.jetty.util.Utf8StringBuffer

public class Utf8StringBuffer
extends Utf8Appendable

UTF-8 StringBuffer. This class wraps a standard StringBuffer and provides methods to append UTF-8 encoded bytes, that are converted into characters. This class is stateful and up to 4 calls to Utf8Appendable.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 http://bjoern.hoehrmann.de/utf-8/decoder/dfa/
