copyright character in vim

Question

I used to get this copyright symbol in vim earlier through some keys' combination. Can someone help me with it now? I simply fail to recollect it.

Also, if possible, share some more of such characters... someone might need it sometime.

Answer 1

any help here?

© for the copyright character

Answer 2

Ctrl-K Co

Should do it

Answer 3

:digraphs

shows the list of digraphs you can use. I see the copyright symbol as number 169, which has a key combo of "Co". To recreate that in edit mode, hit Ctrl+k, then type "Co", and you should have a copyright symbol.
