    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.
