Sometimes you have an uncontrolled amount of text in a horizontally constrained space.

The wrappable filter places zero-width breaking spaces into the given text so that it can wrap at any point, as necessary for the containing width. Sometimes better than eliding (chopping long text...) or cropping/scrolling overflow.

    Places zero-width breaking spaces in text to allow it to wrap at any point.
    
    Munges text into HTML, so should be used last in the filter chain.
    {{ user_generated_text|wrappable }}
    """
    return "​".join(value)
register.filter('wrappable', wrappable)
