Automatically replace &nbsp with space

In my WooCommerce online store, I frequently copy and paste product description from the OEM webpage. This works well for the most part, however depending on the site, the spaces are sometimes encoded as &nbsp. While this renders just fine in the browser, it does cause issues with text wrapping as the browser appears to see the string as one long word (so the text will inevitably overflow, unless I use word-break which will just break words in the middle).
What I’d like to have, ideally, is something that automatically converts these &nbsp to a regular space character. Is this possible, are there any downsides and what are other solutions to consider?

How to add a shortcode function that returns the taxonomy slug of the actual post within the loop

Circumstances: I have a CPT called “designs” and a taxonomy related to it, called “project_category” so that I can assign a category to each design. I’m building the template for each ‘design’ and I need a shortcode that returns the assigned project category SLUG of the current design within the loop.
