As Erwin said in reply to your post here, you can use a hex editor to see what font tables are contained in the file. IrfanView (free for non-commercial use) includes a hex viewer, invoked by pressing the F3 function key on your keyboard; I seem to remember that there is also a High-Logic hex editor or viewer, but I can’t find the link right now.
Edit: The file ‘ViewHex.zip’ is attached to Erwin’s post here.
