When I try to fill a QComboBox with non-English strings (i.e. containing stressed characters like é,à, û...), I don't obtain the same result if I use QComboBox.AddItem() method in a loop that if I use QComboxBox.AddItems() method.

QComboBox.AddItem() method produces valid display : stressed characters are left untouched.
QComboBox.AddItems() method convert stressed characters to another encoding (don't know which one, but it's not Utf-8) producing garbage display of strings in combo box.

Here is a simple example :

var mainWindow=new QDialog();

var list=new List<string>();		
list.Add("ASCII - Coder une adresse e-mail");
list.Add("Base64 - Transmettre des données binaires");
list.Add("HTML - Caractères éligibles en entités HTML");
list.Add("LowerCase - Caractères alphabétiques en minuscules");

var combo1=new QComboBox(mainWindow);
foreach(var item in list) combo1.AddItem(item);

var combo2=new QComboBox(mainWindow);
combo2.AddItems(list);

combo1 and combo2 have not the same display !!!
