Hi. As the title says, I can’t use _ in any filename. I have a bépo layout. To enter «_» I have to press alt gr + space. When I do that, I have a drop-down menu appearing with various filenames.
The keycode pressed are : «17(ctrl), 18(alt) 32, then 95», or, in «UI event» : «ControlLeft, AltRight, Space» (I got theses information from Keyboard Event Viewer).
