Sorry I should have said UTF-8 (mathematical) characters.

I don't exactly but one way to try look into this is how does LaTeX do
it when rendering  mathematical formulas to PDF. Not sure if rendering
is the right here but I hope you get the point.

One example for rendering mathematical formulas in UTF-8 characters can
be seen in the PDF linked on this site:

Section 10 shows a Latex mathematical completely made of characters.
