docs: Writes multiple strings to a channelBuffer with the length of the string
  preceding its content. So if there are two string <code>Hello</code> and
  <code>World</code> then the channel buffer returned would contain <Length
  of Hello><Hello as appropriate charset binary><Length of world><World as
  UTF-8 binary>
  
  @param charset
  The Charset say 'UTF-8' in which the encoding needs to be
  done.
  @param msgs
  The messages to be written.
  @return {@link ChannelBuffer} with format
