On our project, from time to time, some users on Windows report that just before the display of a new window they receive a message dialog “unknown encoding”, which proposes them to pick a font. If I understand correctly, whatever they do, the window eventually is displayed fine. See such dialog:
I have a feeling that it comes from the use XRC. However, I’ve now made sure to remove all “UTF-8” in XRC, and it still appears. Frustratingly, we can’t reproduce it.
Any idea what is causing this dialog box, and how can we avoid it?
