Hi I tried to specify the boost::filesystem3::path to use my custom string (icu based) but in result I have error during my code compiling and I can't solve it... I have this issue under Linux, because under Windows ICU has equal with boost char-representation (wchar_t), but under Linux these values are different. The attach has error-screenshot and part of code which has conversion specification etc... Please, help Thanks -- Iurii Gordiienko
