Yes, the bullet glyph is part of the contents of the PDF. Note that the
structure tree is purely informative, and does not affect how things are
rendered. Therefore if a bullet is to be shown, it must be part of the
page command stream.

The “pdfstructtohtml” could be indeed be a bit smarter and do one of
(or a combination of both):

 - Checking the beginning of the text string and, if one of the usual
   bullet symbols is used (circle bullet, square bullet, etc), do not
   output the glyph inside the <li> elements and let the browser add
   the bullet.
 - Removing the bullet from the <li> elements using CSS, so the bullet
   glyph from the text is shown.
