Test and implement std c++ implementation for unicode support

Unicode tables consume big part of Qt binaries. C++11 brings std::use_facet which could be used in example for case conversion. Task is to create prototype implementation and provide the implementation if seen beneficial.

Benefit might come from that the tables are located in commonly std libraries instead. Also other performance metrics(ie. conversion speeds) might be measured.

This is just and suggestion, which can be killed before started
