windows - QT5 Unicode argument works in IDE but not in final exe? -

when pass same unicode argument qt5->projects->run app works, fails if passed argument directly exe. arguments being passed webpage encoded using encodeuricomponent in javascript.

the code is:

    int main(int argc, char *argv[])     {         qapplication a(argc, argv);           if(a.arguments().count() < 2)         {             qfatal("no argument provided");             return exit_failure;         }          qstringlist args = a.arguments().at(1).split("####");          qstring param1 = args.at(1);         qurl downurl = qurl::frompercentencoding(param.tolocal8bit()); ..........     } 

figured out, using param.toutf8() in above code fixes this.
