Upside-down text uses no formula at all — it's a hand-curated list of existing Unicode letters (mostly from the IPA Extensions and Latin Extended blocks) that happen to look like rotated versions of the regular alphabet, e.g. ɐ for rotated a, ן for rotated L.
01 Step by step, per platform
A real, followable procedure for every platform — not a thin restatement of the shortcut.
How it works
- Each letter is individually mapped to an unrelated character chosen purely for its rotated appearance — e.g. lowercase e becomes ǝ (U+01DD, TURNED E), lowercase y becomes ʎ (U+028E, TURNED Y).
- Some letters have no good rotated look-alike (like Latin lowercase r or m have imperfect matches), so generators use the closest available substitute, not a perfect mirror.
02 FAQ
Why does my upside-down text look wrong for certain letters?
A handful of letters (like r and m) have no clean 180°-rotated equivalent anywhere in Unicode — generators substitute the nearest visual approximation, which won't be pixel-perfect in every font.
Will "fancy text" work everywhere I paste it?
Mostly, since it's just Unicode text — but it isn't accessible: screen readers often can't pronounce these look-alike letters properly, and browser find-in-page / site search won't match them against the real word, since each is a different code point from the plain letter it resembles.
