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.

    .. 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.
