Has anyone actually used the interrobang, or seen it used? I'm speaking about the "newest" Latin-based character which is a combination question mark/exclamation mark. I don't know of many typefaces that contains this glyph as part of its set, although it is included in the Calibri typeface which is the default font for Office 2007.
In InDesign, you can find this glyph if you open the Glyphs panel and choose to show "Punctuation."
I'm attaching this glyph to this posting.
