A font for parents with young children so that they can spell out the words they don't want them to hear. Lowercase is as normal. Upper case spells out words.
The Roman alphabet has far too many letters. 9 letters can be represented by combinations of others. This font resoves that problem. Letters replaced: FJKQVWXYZ, Letters used to replace them: BCDEGHIPSU, Other Letters: ALMNORT. Regarding V and B, instead of replacing V with BH, I could replace B with PV (which would be better).
Now that I have the set of letters down to 17, they can be stored in Hexadecimal. So the final alphabet is ABCDE.GHI..LMNOP.RSTU..... Punctuation - 13 symbols: ,-`':()<>!?|. 2 slots left over for other stuff. The space has stuff in it. Do I want that?
There are 32 characters - 17 letters and 12 symbols, a space and two empty slots.
