Overview

Babosa has a conflict with the unicode-string_width gem. unicode-string_width defines a module called ‘Unicode`, but Babosa uses the presence of this constant as the sign that it should try to require the `unicode` gem, which will not be present.

We don’t want to introduce the ‘unicode` gem because it depends on native extensions.

This works around the possibility that the unicode-string_width gem may already be loaded by temporarily undefining the ‘Unicode` constant while we load Babosa, then restoring it to its previous state if necessary.

Can be removed once github.com/norman/babosa/pull/42 is merged and released
