To rotate text, the tool reverses the order of the characters and replaces each with a character that looks like it turned upside down, such as ɐ for a, ǝ for e and ʇ for t. Punctuation is flipped as well, so a question mark becomes an upside down one.
Some letters are symmetric and stay the same, and a few capitals use look-alike symbols from other alphabets. The second variant flips the letters but keeps the original order.
No. These are Unicode characters that happen to look like styled letters, so they paste into any app that accepts text, with no font installation. Because they are different characters from normal letters, search and screen readers may handle them differently.
The characters come from several Unicode blocks and fonts draw them a little differently.
Paste the flipped text and run it again. Most characters map back to the original.
