Editor keyboard input

I have been brought to you because I’m unable to find an answer anywere else. Right now I’m using a keyboard with “bépo” layout (dvorak like for french) and so I wanted to change my settings to make them fit with my own layout. But the problem is that Settings menu doesn’t accept keys like “é” which is at the place of the “z” for me. So I just wanted to know if anyone had this kind of problem and if there was a solution for it other than changing my layout or keyboard.
Thanks for those who can help and sorry for my bad english.
