My vote is for ascii 253
C²U²Sy²C²

Clear enough to read, but harder to type (especially on a phone)

I was championing bolded text that'll screw up spreadsheets.
CUSyC

Besides the spreadsheet issue (which is already enough of a problem), it can also be a bit harder to see the difference.

Math would suggest prime as a better option:
C'U'Sy'C'

Succinct, clear, and easy to type. I like that one.
