This is the RedHat list not the Fedora list!

The problem might be with unicode.  

The regex is wrongly constructed anyway `A-z' should be `A-Za-z'. 
(Even though A-z works in ascii - with a few extra characters
thrown in - it's not going to work in every language locale).

To see if unicode is the problem you could try this:

   export LC_ALL=C

then run your script.  (Or put the line at the top of your script).
