Probably because different kinds of string processing can work more  
efficiently with one or the other encoding. Anyway, why it is the case  
is moot: the fact is that this is possible (regardless of whether you  
use UTF-8, UTF-16 or UTF-32) and therefore you have to deal with it  
when you use unicode.
