Re: ASCII control codes in sequences of multibyte character sets

The last machines I used with bytes not being octets were a Univac 1182
with bytes of 6, 9, 12, and 18 bits, and a PDP-10 with bytes of variable
size from about 2 (or 1?) up to 35 (or 36?) bits. Both machines had 36-bit
words.

The Univac probably didn't call these smaller chunks bytes, but the PDP-10
definitely did.

The Univac used 9-bit quarter words to hold ASCII strings, while the PDP-10
packed 5 7-bit bytes into a 36-bit word to represent ASCII strings. Both
systems also used (different) 6-bit character sets for some purposes.
