Thanks for the tip.

On the French default keyboard layout of most distro, this character is
mapped to "Alt Gr + v".
There are probably similar mapping in some other layouts but I don't
know the details.

Well, French translators are used to use non-break spaces instead of narrow non-break spaces because of technical reasons.

I did some testing recently to figure out if we could change our
translations guidelines to adopt nnbsp now and I found that there are
only 2 single bugs that prevents nnbsp to be used massively in French

- A rendering bug in Qt apps (Qt built-in text layout engine?)
- A rendering bug in TTY (kbd)

Of course we could keep non-break spaces or even use regular spaces in
CLI translations, but it's way easier for us to not have to wonder each
time if a string may be displayed in a CLI and so in a TTY.
So we should be able to use nnbsp in any case. Hope you see the
point. ;-)
