The Wikipedia has the following information about this codepoint:

The interrobang (), also known as the interabang ‽ (often represented by any of the following: ?!, !?, ?!?,?!!, !?? or !?!), is an unconventional punctuation mark intended to combine the functions of the question mark (also known as the interrogative point) and the exclamation mark (also known in the jargon of printers and programmers as a "bang"). The glyph is a ligature of these two marks and was first proposed in 1962 by Martin K. Speckter.
