Lol, you don't insert few hundred graphics, you insert only one, which you use on multiple occasions throughout the book. Unless we're talking specifics here... But even if you were to insert the same image a few hundred times (realistically, more like a dozen times or so, tops), the compression will make it seem like you added only one and maybe a few more bytes that reference the other 11.

If the symbols look ok in Word, you could press the print screen button (next to the F12 key), open up Paint or your favourite image editing program (like Photoshop, Gimp, etc), Edit -> Paste and crop just the symbols. No matter what font they choose, images display the same.
