I understand that, but there is a conceptual difference between classic strings and
unicode string. For instance to make to_upper algorithm, former one needs locales,
while the second one has toupper functionality inbound. 

I can imagine a way how to make these two compatible, question is however if it
won't compromise natural properties of specific string representations.
