Valid points, yet none of these is a design issue of the C++ standard library 
per se. You can write the example you mentioned earlier in this thread in a 
correct and reasonable way in C++, unlike in C. But developers need to be 
educated how, and I think this library can help with that by increasing the 
general awareness of localization-related issues in the C++ community.
