Can I search for a Unicode combining character in Vim?

Question

I have a file with the character ã (lowercase a + combining tilde). Encoding and fileencoding are both utf-8. ga shows

<a> 97, hex 61, octal 141 <~> 771, Hex 0303, Octal 1403

(but with the actual combining tilde in the <>) and g8 shows

61 + cc 83

Searching with /a\%u0303 works fine.

Searching for just \%u0303 gives E486 Pattern not Found.

Can I search for just the combining character without also searching for the base character?

Answer 1

Type in normal mode /<ctr-v>u0303
/ - start search
<Ctr-v>u - init utf-8 code input
0303 - hex code combine character.

:he unicode

Also :he mbyte-combining and :he utf-8-char-arg the last one covered case with commands like f, F and so on.
