First off I want to say I'm aware this may sound like a feature request, but even though the game is working as intended, this is a very long running issue caused by a small oversight.

The problem is Italian keyboards lack the tilde key (as you can see in this image), indispensable for entering relative coordinates when writing commands.
Up until recently I didn't mind it too much since I only use commands occasionally, but then I realized this issue might be a big annoyance for other Italian players who are a lot into this part of the game.

My current workaround is to use Windows' hotkey to swap keyboard layout to English, enter the ~ character and switch back to Italian, but even then, it's 6 or 7 keystrokes just to enter 3 characters. I'm "lucky" enough to know about this method, but I'm sure a lot of people don't and have to go through copy the symbol from elsewhere out of the game and paste it in every time they are working with commands. Easy to see how tedious it can get.
Changing OS settings or even having to alt-tab out of the game in order to use a game feature seems very odd and out of place to me.

The best solution I thought of is having an additional symbol for relative coordinates (perhaps ^) without altering the current syntax everybody is used to. This way you can make Italian players happy without negatively affecting the rest of the userbase. Win-win.

Summary of the bug:
What I expected to happen was...:
I was able to use command features without the aid software external to the game.

What actually happened was...:
I was unable to enter relative coordinates because my keyboard is missing the ~ key.

Steps to Reproduce:
1. Go in your OS settings and change keyboard input language to Italian.
2. Enter the command /tp ~10 ~20 ~30.
3. Find yourself unable to type ~.
