Of course drawing all the letters with a vector brush is a nightmare. But many strokes are repeated or very similar. Starting with a square calligraphy which is simpler, the round is easy to get:
With some guides, repeating strokes, regulating distances ...
...someone can make a font:
I know it's not a solution, but maybe an idea, or at list some information.
