In a dynamic language like PHP it's a very normal and basic case 
handling language features dynamically including the one described in 
the bug report (Find an upper case constant for the given input). What I 
mean is that we should have basic functions addressing this. So for 
example we need a basic function to upper/lower case only ascii characters.
