Jumping in! I too would like to do this. A '?' question mark is not allowed in a file name along with seversl other charactors. I would like to show a ? in a filename. Eg, if you type (hold down 'alt') & type 0191, you get ¿. If you could re-map it so as it appears as a ?, its a ? but its not really,it just appears so.
(''alt+ 0176 = ° degrees its 96° right now! - alt 0178 = ² squared, 4² =16, etc, etc)
Duckiduckgo asci. - alt codes, etc, , ,
