I think the font problem was with the symbols, especially the arrows. In the Kindle version they were replaced with dots or something else. I don't think we need to be worried about which particular fonts were used. On the Beacon Star Facebook page, the downloadable PDF is even clearer than this image. I wonder why he left the cursor on the cell with a "T" in it in this image?
Thanks for that clarification TxTH.... you're such the puzzle king.
