Huh?
Only meaningful objection I've heard is a problem about 
multi-thread multi-locale program.

And as I already said, the Xutf8 API doesn't solve the problem. 
The only option to solve this problem is to make (very few) APIs
which have explicit locale argument.

In other words, Xutf8 APIs don't solve real problem, don't add 
any new feature, only add incompatiblity and make code bloat.
