Using Gimp and some old scripts (attached)
First what do you know about Gimp and unicode. Every character has a code including those that are not on the regular computer keyboard. You can get these in Gimp by holding shift-ctrl-u then enter a code.
Lists of unicode categories https://www.compart.com/en/unicode/category
You will need to make your shapes using paths, which is not a bad idea anyway, various tools for that, I use the attached script shape-path.scm but Ofnuts has a comprehensive tool in http://sourceforge.net/projects/gimp-pat...s/scripts/ ofn_path_to_shape
A quick video demo:
