Not really, I haven't set any locale on my servers intentionally. Or
rather, left it at the "POSIX"(?) default during d-i.
$ localectl status
System Locale: n/a
VC Keymap: n/a
X11 Layout: de
X11 Model: pc105
X11 Variant: nodeadkeys
$ cat /etc/default/locale
#LANG="C"
$ env | grep LANG
$ env | grep LC_
$
With both LC_ALL=C and LANG=C it shows at least some indication that
there are other characters. But why not when no explicit locale has been
set?
