Thank you.

Answer 1

How did you try to convert the string so far?

According to documentation std::string QString::toStdString () should convert the unicode-data to an ascii-string

But be warned that you loose special-chars which ascii can't handle.

Answer 2

According to Qt documentation, QString::toStdString internally uses toAscii() function: http://doc.qt.nokia.com/latest/qstring.html#toStdString

Basically, you'll need to make your own converter function that would use QString::toUtf8() instead.
