Why is not wildcards unfolded as expected if LANG is ja_JP.UTF-8

  Hi.

  I can't expand wildcards as expected if I use 'setenv LANG ja_JP.UTF-8'.
  For example,

% mkdir test
% cd test
% foreach a (a b c d e A B C D E)
foreach? touch $a
foreach? end
% ls
a  A  b  B  c  C  d  D  e  E
% setenv LANG ja_JP.UTF-8
% ls [b-d]
b  B  c  C  d                           <=== It's not good.
% env LANG=ja_JP.UTF-8 ls [b-d]
b       B       c       C       d	<=== It's not good.
% env LANG=C ls [b-d]
B       C       b       c       d	<=== It's not good.
% setenv LANG C
% ls [b-d]
b  c  d					<=== It's good.
% env LANG=ja_JP.UTF-8 ls [b-d]
b       c       d			<=== It's good.
% env LANG=C ls [b-d]
b       c       d			<=== It's good.
%

  This happens on 12-current and 11.2-RC3. I'm using tcsh but the same
when changed to bash.
