public final class StringDecoder extends AbstractDataBufferDecoder<String>
String stream. Before decoding, this decoder
 realigns the incoming data buffers so that each buffer ends with a newline.
 This is to make sure that multibyte characters are decoded properly, and do not cross buffer
 boundaries. The default delimiters (\n, \r\n)can be customized.
 Partially inspired by Netty's DelimiterBasedFrameDecoder.
