Move KB-H047 - Non ASCII

[uilianries]

As we are running only Python 3 and C3I requires Python <= 3.6, we can accept non-ascii characters in recipes.

I also removed Python 2.7 testing for Windows. Why? We no longer run Python 2 on CCI.

UPDATE:

Now non-ascii is a separated hook.

Why not moving it out from conan-center hook to its own hook? This is a feature that some people might find useful.

@jgsogo Good idea, I'll do that

[SSE4]

you can remove py27 altogether from CI (e.g. tox.ini and whenever else it's mentioned)

[uilianries]

For some reason, on Windows the output messages are not there. Need to investigate further

Fixed!
