Well there's the enable_formatting keyword to IDLgrText::Init:


    Set this keyword to indicate that the text object should honor
    embedded Hershey-style formatting codes within the strings.
    (Formatting codes are described in Fonts.) The default is not
    to honor the formatting codes.

I know that this causes positioning codes like !E and !N to be recognised
(with TrueType as well as Hershey Fonts). I've never tried the codes to
select different fonts.
