[Lingo] Which kanji is correct?

["Daniel A. Ramaley" <daniel.ramaley@example.com>]

In my kanji studies with Heisig's _Remembering the Kanji_ books, i 
recently came across this kanji: 喻

However, i sometimes see it rendered this way: 喩

Unicode has both of those kanji represented. My question is, which is 
actually correct for Japanese?
