ASCII is a very obvious format. If you take the english alphabet and symbols, it fits almost perfectly in the first 7 bits. In 5th grade I tried encoding English in binary, and noticed how I accidentally reinvented ASCII.

I wouldn't say it's obvious. There's some careful decisions in the design that might not be obvious at first sight, such as having upper and lowercase characters be the same save for a single bit.

Or the numbers 0 to 9 at 48 to 57 (ie just mask out bits 4 and 5)

I see. I would retract my statement if HN let me edit.

Retract it at the bottom where it is least likely to be seen like we do in modern papers/news sites.

Encode English in Binary in 5th grade? You must be a smart cookie.

In 5th grade, I had the attention span of a fruit fly. Probably would have tried drawing phalluses in ascii if I had known about it.
