Need simple Find/Replace script searching for bullets, Word 2008

I’m trying to make a few simple Find & Replace scripts but they don’t seem to work to well. I need to search for bullets (option-8) and it only seems to work sometimes strangely. The script I’m using is:

tell application "Microsoft Word"
	set findRange to find object of selection
	tell findRange
		execute find find text "●^t" replace with "" replace replace all
		execute find find text "● " replace with "" replace replace all
	end tell
end tell

Is there some ascii code or something for bullets? Thanks in advance for your help,
