NetBSD netbsd11 11.0_RC6 NetBSD 11.0_RC6 (CUSTOM_SCTP) #0: Thu Jul 23 15:24:45 UTC 2026  root@:/usr/src/sys/arch/amd64/compile/CUSTOM_SCTP amd64
>Description:
When logged in via SSH session, NetBSD 11.0_RC6 produces an invalid separator for printf "%'d\n" when the locale is set to nb_NO.UTF-8.

Example:
$ LC_ALL=nb_NO.UTF-8 printf "%'d\n" 12345
12&#65533;345

The separator should be a space in Norwegian locale (nb_NO.UTF-8). Instead, it sends &#65533;.

$ LC_ALL=nb_NO.UTF-8 printf "%'d\n" 12345 | hexdump
0000000 3231 33c2 3534 000a                    
0000007

In the console, the "&#65533;" is shown as space, so the issue is not visible there.


For example in de_DE.UTF-8, the output is correct ("." is used here):

$ LC_ALL=de_DE.UTF-8 printf "%'d\n" 12345 
12.345

>How-To-Repeat:
$ LC_ALL=nb_NO.UTF-8 printf "%'d\n" 12345
12&#65533;345
