Huh, that works well if we know the input string is in Turkish. What if this information is not available as you're writing the code?

And what will lowercase()/uppercase() be hard coded to do, and what are they supposed to output when the input isn't ASCII?

Give me an example. I'll try to find the best -IMHO- solution.
