Improve Compatibility

[olls]

Particularly with Unicode characters, they should switch to ASCII instead of erroring. Also the different modules such as colors, console and nbinput should test if possible if they are working and if not fail gracefully with fall backs.

• colors.py
• console.py
• nbinput.py

Looks very similar to the one I'm using, it uses the same modules, I don't know if it has better compatibility, I havn't tested my current one on windows yet.

This one has compatibility for Unix and Windows. It works in Linux, haven't tried in Windows.
