*sigh* Yes, what he says is correct. Now to do something with 
strings. I.e. reverse them, or any other operation that needs to split 
the string into pieces.

Try to do any operating with has to do with the order of characters (i.e. 
compare strings).

Now the model "be ignorant" no longer works.

If all you did need to do was nothing, people wouldn't be begging for 
Unicode support, right?
