try this
ls [a-b,k-m]
in sh using the locale setting to pt_BR.UTF-8
it's not work
# locale
LANG=pt_BR.UTF-8
LC_CTYPE="pt_BR.UTF-8"
LC_COLLATE="pt_BR.UTF-8"
LC_TIME="pt_BR.UTF-8"
LC_NUMERIC="pt_BR.UTF-8"
LC_MONETARY="pt_BR.UTF-8"
LC_MESSAGES="pt_BR.UTF-8"
LC_ALL=
# ls [[:lower:]][a-c,k-m]*
aa
# ls
a b d f j m p t x
A B D g k M q u y
aa c e h K n r v z
Aa C E i l o s w Z
#
It's not show the correct list, this commant MUST BE SHOW like a C
locale
# locale
LANG=C
LC_CTYPE="C"
LC_COLLATE="C"
LC_TIME="C"
LC_NUMERIC="C"
LC_MONETARY="C"
LC_MESSAGES="C"
LC_ALL=
# ls [a-c,k-m]*
a aa b c k l m
# ls [[:lower:]][a-c,k-m]*
aa
#
When I try to use the poor workaround [[:lower:]] or [[:upper:]]
this have too different behavior. The list replacement not work
properly
Note, I know that Unicode have some differents, but when tha basic
list replacement
and other basic default behavior must be preserved.

It's a great problema yes!, the default shell in FreeBSD to user root
in fresh new installation is csh, look the passwd file
root:*:0:0::0:0:Charlie &:/root:/bin/csh
and it's will be great problem because all man pages with
trate a list substitution not say anything about this.
