Here's how ya do it (just to annoy zeddy lol)

Unlike in previous entries when I was all like "Staffie Magic. =P" or "SECRET STAFFIE MAGIX. B)", it's not actually staffie magic lol

1. Wiki the letters you want (v, for example)

2. Go to the "See Also" section (or the diacritics section in the template)

3. Copy/pasta whichever character seems close enough to the one you want (the Greek ν [pronounced ni FYI], for example)

4. ?

5. bankruptcy Profit!

(...though I'm sure there are more effective ways of doing it. xP)
