As the title says, it seems that spamming of unicode characters in the site chat is still a problem when it really shouldn't be. I propose we strip any non-standard characters from chat messages to prevent issues such as these

From arising.

I know this was mentioned before but I can't seem to find the thread.

Anyways, this is what people call Zalgo, and it is being investigated by the devs. From what I recall, it's a bit more complicated than a simple restriction.

Zalgo is a site to generate things such as this from normal text, see: http://eeemo.net/
 
Wouldn't it be easy to create a "whitelist" of sorts for characters and anything that isn't on that list would be stripped?
 
Edit: A regexp such as this should work fairly well. 

if ( preg_match ( '/[^\x20-\x7E]/', $text ) || preg_match ( '/[^\x20-\x7E]/', $text ) ) 
{
    die('ZALGO not allowed');
}
