I though that this count be done with the use of tr() but I was wrong...
I am trying to place this text to a button:
Déplacer à l'image &suivante
In french it means "Move to Next image". I place this text into the button with this way:
ui->nextButton->setText(tr("Déplacer à l'image &suivante"));
The Qt Creator, after compiling, show the button's text like this:

As you can see the special character is shown wrong. Is any Qt can recognise these special characters?
