*OF*COURSE* it doesn't.  Unix is _case_sensitive_.  You specified a lower-
case only (in the C locale) pattern.  Naturally, it doesn't match a file 
with an upper-case character in it.

Note: in the 'C' locale, characters are sorted on the underlying byte value.
Thus you will get all the upper-case matches before any lower-case match.

To get upper-and-lower case files in the C locale, you will have to use:
          ls [A-CX-Ya-cx-y]* 

IF you speciy a different charset for collating, you _may_ get upper/lower
case characters sorted adjacently.  See the specifications for the charset
in question.
