Make unidecode optional in sanitize methods

Allow to sanitize text from non English websites without losing data.

This is not backward compatibility as I believe this should be the default behavior in most cases.

Maybe unidecode could be a pipe of its own?

I think sanitize | unidecode (or sanitize | ascii_safe) is more readable than sanitize(ascii_safe=True)

Yes, I think your approach is actually better.

I have implemented the method ascii_safe. I tried implementing it with unidecode but it looks like there was some name collision issue between the shublang name method and the unidecode method itself.

If you are able to fix it we could use unidecode instead. I don't really have a strong opinion on which one is better.
