Hey! Here's some more fun: an interactive version of these layout diagrams.
It's in SVG format. It will work on Firefox, Chrome and Microsoft Edge, probably others.
Since the forums won't upload SVG, I've renamed them XML (which is actually what SVG files are).
My Firefox is smart enough to open them and realize that it's SVG.
If your browser can't, just rename them .svg
Just mouse over a letter and it will tell you what Unicode character it is.

Edit: Yet more progress. The official Unicode name for the character will appear when you hover. More fine-tuning.
