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
