Note: the NBS character is tricky to paste in and retain.  The key seems to be;

1. Copy from this website

2. Select a text box and delete all characters in there

3. Set the required Style, plus any modifications

4. Wait a few moments - so that the undo history can record a point

5. Paste in the NSB

6. Wait a few moments

7. Come out of Edit Text

Now you find the text box has been deleted automatically - just hit CMD-Z (undo) and it should reappear
