My reaction to that was "oh boo hoo".
When people my age were kids (get off my lawn) we used to type pages of raw hexadecimal from the back of magazines into a machine prompt. We didn't cry about it, we were just careful.
I can't find a hexadecimal example at the moment, but look at some of these TRS-80 programs (pp. 110-111, 143) which have multiple pages of data/digits to transcribe:

Btw, the originals were often bad photocopies. So maybe not 4 point font, but certainly ambiguity in some bits.
