Tsk! It's even in Wikipedia:
ANSI X3.26 – 1980/R1991) Hollerith Punched Card Code
Unfortunately, the document is still locked up by ANSI, but the code
itself is documented about midway down
http://www.quadibloc.com/comp/cardint.htm That page shows a full
8-bit punch card code. Hmmm, which means it can be used to punch
UTF-8 representations of Unicode...

Tsk! I read in
1. No text beyond the 72nd column of a line. This is especially
important for diagrams and code, which the RFC Editor may not be
able to trivially reformat to fall within the margins.
5. ASCII-only, no control characters (other than CR, NL and FF).
And where do you think the 72-column rule came from? This is so the
line can be centered on an 80-column display, which is a lineal
descendent of the 80-column Hollerith card.
Indeed, the RFC series is probably the *only* modern document series
that can reliably be punched on cards!
