How does the flipped text magic actually work?
An upsidedown text generator does not rotate an image or install a font. It reverses the source and replaces supported characters with Unicode look-alikes that resemble vertically flipped letters, numbers, or punctuation. The result remains selectable text that you can copy and paste.
Unicode does not provide a perfect inverted form for every character. This tool keeps an unsupported character unchanged instead of guessing. In our browser test, é and 😀 were preserved, while supported characters in Abc 123!? were mapped and reordered.
