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
