I don't recall having seen either.  I have seen kg and km in the wild
in Monkasho documents, the roman numerals (a related JIS-ism) are very
commonly used in Japan by people in my department with certain boxen
(I think it's Fujitsu FMV) and maybe by staff preparing agenda and
minutes, and I'm pretty sure I've seen the occasional "4-square"
character.

I believe you can thank JIS for that; IIRC they're classed as
compatibility characters.
