See the "By character value" section in: http://vim.wikia.com/wiki/Entering_special_characters

You'll need to determine the character code first though, there should be character map application in your distro.

The Unicode for "Black Diamond Suit" is U2666. As kbp mentioned, look under the "By character value" section of the cited article, where you read:
Quote:
By hex value for BMP Unicode codepoints: ^Vunnnn (with 0000 <= nnnn <= FFFF)
First you have to go into Insert mode, then in sequence Ctrl-v, u, 2, 6, 6, 6. You will not see anything on the screen except the ^ sign, but after completing the sequence a black diamond appears. Hope this helps.

Maybe your terminal doesn't support UNICODE character set. Which terminal are you using? If gnome-terminal (the default in Red Hat with GNOME desktop) check under the menu Terminal --> Set Character Encoding and see if Unicode (UTF-8) is there and selected.
