What 🙮 means
The Wingdings rocket glyph was made to sit alongside ordinary text. The Wingdings family was designed in 1990–91 from symbols made to pair with the Lucida typefaces, a family of regular text fonts, then released by Microsoft in 1992 as Wingdings, Wingdings 2, and Wingdings 3. Its creators describe the marks as informational, expressive, or decorative, with direction and emphasis chosen by the typographer. A 2011 Unicode paper maps this design to Wingdings entry 0248; Unicode encoded it as text in 2014, so it can travel without the original font map, though a font still has to draw it.
Decorative and typographic; its rocket shape can suggest direction, but the context supplies the job.
