[57north-discuss] Help with an ancient greek keyboard?

Hi all, I'm a newbie to programming/3D printing and I've had a project in mind for a while- making a bluetooth polytonic greek keyboard. A unicode block for polytonic greek is available (https://en.wikipedia.org/wiki/Greek_Extended), but as I'm a novice I don't know if this would be helpful for creating my keyboard. I guess I need help in the following: 1) What to buy 2) 3D printing polytonic greek keycaps 3) Ensuring that what I type on the keyboard comes out as ancient greek on my computer Any help/guidance on this project would be much appreciated! Kind Regards, Jamie
