Correct, except that there

Thanks for all the interesting feedback.

10646, what were the smallest and largest size code units ever used for
representing character data? In the various responses, there was reference
to 6- and 9-bit character

Any characters bigger than 9 bits smaller than 6?
Of course, Baudot was 5-bit code used widely in Teletype networks,

something like GB2312 were encoded in a flat (linear?) encoding that never
used code-unit sequences, the code units would have to be larger than 9

until its retirement in the Fall of 1990. I recall it with great

Line break is not a character. It is number thirteen, though, isn't it?

Life is assuredly better today when word sizes, other than on some
embedded processors, are now uniformly multiples of 8 bits, and
characters are numbered starting from 0.

On the 36-bit PDP-10 architecture, a byte could be any size from 1 to 36

On DEC-10, with a 36-bit word, a byte was anywhere between 1 and 36
