This may require much more work than to simply keep [nbsp] for a
while...

We can start using [nbthin] everywhere and, if we find that it causes
trouble in some apps, we can use instead [nbsp] while the underlying bug
is being fixed.

This may be longer but IMHO this is easier.

Yes, this is exactly what my patch implements. ;-)

But, as an addition, a "visual tag" to represent [nbsp] or [nbthin]
would be great too.
The current implementation is not clear for beginners, I see quite often
translated strings (eg "Bonjour[nbsp]!") with newly proposal with a
standard space instead of "[nbsp]".

With a small picture to represent it, it may be clearer and, by
questioning the user, it may encourage him to read translations
guidelines.

(perhaps this need a specific bug report?)
