I reproduced the problem. My default locale is en_US.UTF-8.
When I use:
LC_ALL=en_US.iso-8859-8 egrep -n '[A-Z]'
the lowercase letters are not matched.
It is still mysterious to me why egrep (or grep) folds lowercase into uppercase when the locale is UTF-8.

In the commands below I insert data to grep via standard input and terminate with <Ctrl-D>. Lines that match the expression are echoed back. To improve visibility I used -n option so we can see the line number of the matched line. BUT.
Can anyone explain the following behavior?
Did anyone fiddle with the weight of letters?
