Click attempts to support both Python 2 and Python 3 the same way and to be very robust even when the environment is misconfigured. Click wants to be functional at least on a basic level even if everything is completely broken.
What this means is that the echo() function applies some error correction in case the terminal is misconfigured instead of dying with an UnicodeError.
As an added benefit, starting with Click 2.0, the echo function also has good support for ANSI colors. It will automatically strip ANSI codes if the output stream is a file and if colorama is supported, ANSI colors will also work on Windows. See ANSI Colors for more information.
If you don’t need this, you can also use the print() construct / function.
