以下のように、String#rpartition に正規表現を渡したとき、マルチバイト文字列だと挙動がおかしいようです。

 # encoding: UTF-8
 "user@domain".partition("@")     # => ["user", "@", "domain"]
 "user@domain".partition(/@/)     # => ["user", "@", "domain"]
 "user@domain".rpartition("@")    # => ["user", "@", "domain"]
 "user@domain".rpartition(/@/)    # => ["user", "@", "domain"]
 "ユーザ@ドメイン".partition("@")  # => ["ユーザ", "@", "ドメイン"]
 "ユーザ@ドメイン".partition(/@/)  # => ["ユーザ", "@", "ドメイン"]
 "ユーザ@ドメイン".rpartition("@") # => ["ユーザ", "@", "ドメイン"]
 "ユーザ@ドメイン".rpartition(/@/) # => ["ユーザ@ドメイン", "@", nil]
=end
