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

ENABLE_FORMATTING (Get, Set)

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.
