Fancy Plaintext Checklists

Make a list like this:

• Item One
• Item Two

And check them off like this:

• √ Item One complete
• × Item Two invalid, for whatever reason

The check (Unicode U+2713 is easy to type on OS X, just do ⌥-v.

The × sign however is a bit tricker and is the unicode character U+00D7. This can be typed in vim by doing the following (in insert mode):

Ctrl-K, Shift-8, Shift-X

Sort of annoying but fancier than plain x!
