Can the List of Bullets in a Paragraph Style be accessed using Javascript

I keep getting asked if I can check all the fonts in a document and find and list any that aren't being used but exist in the document anyway. One area is the Bullets and Numbering section of the Paragraph style where bullet characters can be created that remember their fonts. This must create a list that is stored with the document. The bulletChar gives access to the bullet that is selected in the style but I can't find anyway of accessing the list of bullet characters. A friend viewed a file as an xml document and the bullets do show up with a tag of <ABullet>. I was woundering if anyone could help or if it's not possible could you explain what that list is doing?
