Likewise I seriously considered adopting NNBSP, that is very important
as a layout control, e.g. in the fr-FR locale, and is almost always stable
in the applications, as opposed to NBSP. Indeed neither do I see any

a visible representation, displaying their abbreviation in a box.

However I was aware from the beginning that my desire was unconventional.
