     Thanks for reply!

      I meant LC_COLLATE being  set to en_US.UTF-8 not C.  linux and 
solaris  shows both  upper and lowercase when set characters like 
[a-cx-y] and others   are used. when LC_COLLATE is set to  en_US.UTF-8.
      I thought it could be also done in FreeBSD's  bash  when   
LC_COLLATE  is  set to en_US.UTF-8

     in linux LC_COLLATE is set to en_US,UTF-8
     eam at localhost ~/testdir $ locale

     And when i type the following it shows both:

     eam at localhost ~/testdir $ ls [a-cx-y]*
     bincar  Bincar

     eam at localhost ~/testdir $ ls [a-z]*
     bincar  Bincar  file  File  zcar
