If you're like me, you often go through many pictures, audio and video that has unique filenames describing the content of the file, and I am usually pissed when I cannot put a "?" at the end of the file and need to leave it as something like "Haddaway - What is love.mp3"
I have just found a character that's simply an upside down "?" and windows doesn't care! Now I can properly name my files.
To use it, just simply copy and paste this: ¿ Or you can just hold down ALT and type the numbers 0191 and let go of ALT to put it in.
