Convenience helpers function Tools::toStdString and Tools::fromStdString were implemented for Qt4 or older to perform utf8 aware conversion as QString::toStdString/QString::fromStdString were using toAscii/fromAscii internally (see https://dreamswork.github.io/qt4/classQString.html). Since Qt5 QString uses toUtf8/fromUTf8, which makes the helper functions obsolete (see https://doc.qt.io/qt-5/qstring.html#fromStdString).
