That's the right approach. And we can only hope that at some point soon, 
QML starts feeling more complete. For something that should be the base 
of Qt 5, it's in a pretty sad state.

The other (and better) solution for you is to create a patch that fixes 
this and get it into Qt. Then you are sure that it will work in future 
releases.

For now, you can export functions from c++ that calls the locale aware 
methods and return the result to your QML/JS code.
