Hi rick,

we changead this code in visual studio and now all seems in order...

Ceci  : StreamWriter sw = File.CreateText(Application.StartupPath + "\\" + aNumMut + ".txt");   crée un fichier en utf8 incompatible
  
remplacé par cela :  StreamWriter sw = new StreamWriter(Application.StartupPath + "\\" + aNumMut + ".txt",false, System.Text.Encoding.ASCII);
