This question already has an answer here:
I plan to create a new character system for an existing language. I have the new characteres drawn on paper. I would like to draw them on the computer, save them as custom characters and create a new keyboard layout with them in Ubuntu linux. I have no experience with keyboard-character stuff. How to do it?
Clearly. I have 35 characters on paper. I wish them to be implemented as text characters on the computer. Is there software to draw the characters in linux? And after having the chars created how can man add them to the computers char set?
