 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.
