I found an ASCII version of some characters, are there more ASCII-rendered Unicode symbols?

There’s a couple of lists out there of ASCII approximations of Unicode punctuation, including:

• Lexical Tools
• https://lexsrv3.nlm.nih.gov/LexS…
• Replacing unicode punctuation with ASCII approximations

None of them include (C) and (R), irritatingly.

If you want ASCII approximations of other scripts, you’re getting into ASCII Romanisations, such as Greeklish, Fingilish, 3arabizi, etc.; see Category:Romanization by script
