Using the Interrobang
The interrobang overlays a question mark on an exclamation mark to end a sentence that is both a question and an outburst: "They cancelled the finale‽" It was proposed in 1962 by Martin K. Speckter, a New York advertising executive who disliked the untidy "?!" in headlines, and the name joins interrogatio with "bang", printers' slang for the exclamation point. American Type Founders cut it into the Americana typeface in 1966, Remington put it on a typewriter key in 1968, and then fashion moved on. Unicode preserved it, so every modern operating system now ships fonts that draw it.
How to use it
Place a single interrobang at the end of the sentence with no space before it, exactly where a question mark would go. Do not add a second mark after it, and do not pair it with "?!" — one or the other. Because it signals surprise or disbelief, it belongs in dialogue, headlines, comics and casual writing; formal prose still expects a plain question mark, and most style guides do not mention the mark at all. In Spanish the sentence would open with the inverted form ⸘ and close with ‽, though the inverted glyph is missing from many fonts.
Where it renders
Support is good but not universal. Arial, Times New Roman, Segoe UI, San Francisco, Roboto and Noto all include it, so it displays on Windows, macOS, iOS and Android as ordinary text. Some display faces, custom game fonts and older embedded devices lack the glyph and show a box instead; if that happens, ⁉ from the same block is usually available, though phones tend to render that one as an emoji. Handles on most platforms reject punctuation, but display names and bios on Discord, X and Instagram show the interrobang without trouble.
Typing it
There is no shortcut on any standard keyboard. In Word, type 203D and press Alt + X to convert the code into the character. On Windows generally, open the emoji panel with Win + . and search the Symbols tab. Mac users open the Character Viewer with Control + Command + Space and type "interrobang". Phones need a text replacement — for example, mapping "?!!" to ‽ — or a paste from this page. Because it is so awkward to type, many people keep it saved in a note.
Personality mark
The interrobang has become a badge for people who like typography, and it appears in bios of editors, designers and writers as a small in-joke. It also carries a "chaotic" tone in usernames and Discord statuses, where a name like "why‽" reads as bewildered and playful at once. If you enjoy the look, the ellipsis and quotation marks pages cover the other punctuation people use for tone, and fancy fonts will restyle the letters around it.
