   You draw a line under it.  Sorry, but PostScript fonts do not have underline
   stuff in them, only the info about the character itself.

Not quite correct.  Here is the top portion of Utopia-Regular:

%!PS-AdobeFont-1.0: Utopia-Regular 001.001
%%CreationDate: Wed Oct  2 19:10:38 1991
%%VMusage: 32987 39879
%% Utopia is a registered trademark of Adobe Systems Incorporated.

The FontInfo dictionary for the font may contain UnderlinePosition and
UnderlineThickness.  The Adobe Font Metric Files Specification Version
3.0 has the following to say about this info:

UnderlinePosition number

(Optional.)  Distance from the baseline for centering underlining
strokes. This may be interpreted as a y-displacement for writing
direction 0, and an x-displacement for writing direction 1.

UnderlineThickness number

(Optional.)  This is the stroke width for underlining, expressed in
character coordinate space (proportional to the characters in the font
program.)

   Since you know the starting point of the text, you determine the length of
   the string, drop down a point or two and draw a line of string length.  That
   is a simple way of doing it.
