Reverse text
Reverse text. A classical cipher, computed on your device.
Runs on your device. The file is never uploaded.
Reverse text turns a whole text file back to front, character by character, and prints the reversed string. The split is by code point, so accented letters and most symbols come through whole. A flag or a family emoji built from several code points comes apart instead, and reversing text is not encryption of any kind.
Questions
What exactly gets reversed?
The characters of your text, end to end, using a code-point split so multi-byte characters survive. Words are not reversed individually; the whole string is turned around.
How do I undo it?
Run it again. Reversing twice returns the original text exactly, and there is no key involved.
Does it handle emoji and accents?
Characters are split by code point, so most accented letters and symbols come through intact. A grapheme built from several code points, for example a flag or a family emoji, is split into its parts and will not look the same.
Is this encryption?
No. It is a text operation used for puzzles and for testing how software handles right-to-left content. Anyone can read it by reversing it back.
