Sniff Request: Identifiers should consist of only ASCII characters

[bkdotcom]

This below example is bad for less obvious reason

class 💩
{
	public static $роοр;
}

💩::$роοр is spelled \u0440 \u043e u03bf \u0440 (vs "poop")

Good luck trouble shooting.

Great idea!

Especially, it would be helpful when someone puts Cyrillic с instead of Latin c into a variable.
