Is it used outside English? I don't know about any non-English source, I guess it can be disregarded in translations.

On English, the untrustable Wikipedia (which has no source whatsoever in other languages) says «The interrobang, also known as the interabang [...] is a nonstandard punctuation mark [...] Many writers, especially in informal writing, have used multiple punctuation marks [...] failed to amount to much more than a fad». CentralNotice is not in informal language, IIRC, so even in English this is not too appropriate.
