Gnaborretni: ⸘
The gnaborretni (pronounced: "gnab-or-ret-ni"), is the little known and even little-er used Spanish counterpart to the slightly-more-but-still-relatively-little known interrobang (‽).
e.g.
"⸘Dónde diablos está mi heroína‽"
"Oi, where's me smack‽"
Edit: The gnaborretni doesn't show up on many browsers. Code is ⸘
