Thank you!
I re-ordered the characters by ASCII so I could convert them from spritesheets to arrays and then map them directly to the character code. Maybe I can save someone else the formatting time. The main image is 4x9 and starts with ASCII - 32 (the space character)

3x9 characters (ASCII order: 73, 74, 76, 105, 106, 108, 114)

6x9 characters (ASCII order: 77, 87, 109, 119)
