How can Z͎̠͗ͣḁ̵͙̑l͖͙̫̲̉̃ͦ̾͊ͬ̀g͔̤̞͓̐̓̒̽o͓̳͇̔ͥ text be prevented?

Question

I\'ve read about how Zalgo text works, and I\'m looking to learn how a chat or forum software could prevent that kind of annoyance. More precisely, what is the complete set

Answer 1

Using PHP and the mindset of a demolition worker you can get rid of the Zalgo with the iconv function. Of course that will kill any other UTF-8 chars too.

$unZalgoText = iconv("UTF-8", "ISO-8859-1//IGNORE", $zalgoText);
