How flipping works
There is no “rotate” in Unicode. Each letter is swapped for a character that looks like it turned over (a → ɐ from the phonetic alphabet, e → ǝ, t → ʇ), and the whole line is written in reverse order. A few letters have no good flipped twin and are borrowed from unlikely places (2 → ᄅ is a Korean letter). Screen readers will read nonsense, so keep it for jokes.
Questions
- How do I write upside down on my phone?
- Type above and copy the 'Upside down' line. It is already reversed, so paste it as-is.
- Can I flip it back?
- Paste flipped text into the box and copy the upside-down line again: it flips back to normal for most letters.
