Zalgo Text Generator
This is the zalgo text generator. It allows you to convert normal text into zalgo text which you can then copy and paste. Simply drag the "craziness level" slider to change how corrupted the text becomes.
Zalgo text is made up of glitchy letters like this: W̶̭̽͆̍͘ḥ̵̢̻̜̐͊a̴̞̭̼̦̞̒̆͒͂͠t̴͍̭̙̪̳́̔͑͠͠͝'̷̹̠̀̒̂̑̀͝ŝ̴̢̬̭̩͠ ̶̙̤̺̃̈́̀͛ù̷̡̞̝̟͍́p̴̛̯͎̯̆͠,̸͖́̍͌́́́ ̷͈̬̖͋͛͆͘t̷̢͍̹͚̰̏͑̂͛͋̐ͅḥ̴̞̄̀͆̉ͅį̶͍̊̐͗ś̶͕̆̒̎͊́ ̷̹̙̽̑i̴̞͑̕s̶͈͛̀̈̀̋̃ ̵̢̛̼̞̱̲̺̒ẓ̴̜͚̺̭̈̒a̴̞͐͗l̴̬̖̦̣̱̯̋̈́̉͒͋̏g̵̛̞̰̟͐̑̆̓͛o̷̻̪͓͒̃͂̽ ̵̛̬̖̎t̴̢̪̭͙̏̌̔ͅe̷̼͕͓͍̦͐̈̎͘͜x̴̲̲͋̂́̅́t̷̩̲̳͐͌.̷̯̟͋̎̏̇̉. It's made up of many Unicode diacritic marks on top of words in languages like French and Spanish. Some English words like "cliché" have diacritics (above the "e") because they're inherited from other languages. This zalgo generator, and all others which produce glitchy-looking text that you can copy and paste use these diacritic marks to create the weird-looking text.
The term "zalgo" comes from an internet meme/phenomenon which begins with the conversion of a Nancy and Archie comic into a sort of demonic scourge beginning to take over the characters (Thus, zalgo text is sometimes called demonic text too). Following this original comic strip in 2004, the meme began to take hold with others posting zalgo comics too.
The idea behind Zalgo is that he/she/it represents corruption. Corruption of innocence, corruption of normality, corruption of the world as we know it, the list goes on but you get the idea. Zalgo is the embodiment of that which is right decaying grotesquely into something very wrong.
The corrupted nature of the text has interesting origins. The story starts with the Unicode standard; the standards body which governs all the text symbols that you see on all your electronic devices. Unicode needed to design a system that would work for all written languages, and so it had to consider that many languages have a huge number of possible characters because certain "marks" can be added to characters to adjust their meaning. So instead of specifying millions of different characters, Unicode just specified the basic fundamental building blocks plus a bunch of "marks" that can be added to characters. These marks are called "diacritics", and as it turns out, The Unicode designers never specified a limit to the number of diacritics that can be added to a character. Someone noticed this and decided to play around with adding many more diacritics than reasonable so that the text became distorted and corrupted. This eventually gave rise to scripts that automatically add weird marking to letters and eventually to online translators like this one.
