That one is simple enough, E2 80 AF is UTF-8 for code-point 8239 (0x202f)
a narrow no-break space (which would appear as just a space in a fixed
width font like terminal emulators use).

That is more interesting, for nb_NO.UTF-8 FreeBSD is using a regular
width no-break space (Code point 160, 0xA0), and for fr_FR.UTF-8 they're
using the narrow one that Linux uses.

Is Norweigan intended to be different from French in that way, or not?
(ie: do Linux or FreeBSD have it correct) ?   Or perhaps neither, and
both French & Norweigan should be a normal width no-break space?

If this is to get changed in NetBSD, we might as well try to get it right.

The others don't need comments.
