      """Prints a message plus a newline to the given file or stdout.  On
      first sight, this looks like the print function, but it has improved
      support for handling Unicode and binary data that does not fail no
      matter how badly configured the system is.
  
      Primarily it means that you can print binary data as well as Unicode
      data on both 2.x and 3.x to the given file in the most appropriate way
      possible.  This is a very carefree function in that it will try its
      best to not fail.  As of Click 6.0 this includes support for unicode
      output on the Windows console.
  
      In addition to that, if `colorama`_ is installed, the echo function will
      also support clever handling of ANSI codes.  Essentially it will then
      do the following:
  
      -   add transparent handling of ANSI color codes on Windows.
      -   hide ANSI codes automatically if the destination file is not a
          terminal.
  
      .. _colorama: https://pypi.org/project/colorama/
  
      .. versionchanged:: 6.0
         As of Click 6.0 the echo function will properly support unicode
         output on the windows console.  Not that click does not modify
         the interpreter in any way which means that `sys.stdout` or the
         print statement or function will still not provide unicode support.
  
      .. versionchanged:: 2.0
         Starting with version 2.0 of Click, the echo function will work
         with colorama if it's installed.
  
      .. versionadded:: 3.0
         The `err` parameter was added.
  
      .. versionchanged:: 4.0
         Added the `color` flag.
  
      :param message: the message to print
      :param file: the file to write to (defaults to ``stdout``)
      :param err: if set to true the file defaults to ``stderr`` instead of
                  ``stdout``.  This is faster and easier than calling
                  :func:`get_text_stderr` yourself.
      :param nl: if set to `True` (the default) a newline is printed afterwards.
      :param color: controls if the terminal supports ANSI colors or not.  The
                    default is autodetection.
