How can I detect "stylized" text?

Question

I was wondering if there was a way to detect if a text is "stylized", like these:

ʇxǝʇ uʍop-ǝp!sdn

ⓣⓔⓧⓣ ⓢⓣⓨⓛⓔ

ＴＲＡＮＳＭＩＴＴＩＮＧ

can regex be used to detect those?

(also, sorry if there's a word for those text, I don't know how they're called and I can't find it anywhere)

Answer 1

Those are actually special characters, not stylized text, and you can filter them with a regex like this:

var myText = "abc ⓣⓔⓧⓣ ʇxǝʇ uʍop-ǝp!sdn";
var findSpecial = myText.replace(/[\w\s]/g, ""); // \w is for word chars (letters and numbers) and \s for space; g is for general search (all ocurrences) to replace all regular chars and leave the specials
if (findSpecial != "") { 
    alert("Text has special char(s): " + findSpecial);
} else {
    alert("Text has no special chars.");
}

In this example, the alert will be: Text has special char(s): ⓣⓔⓧⓣʇǝʇʍ-ǝ!
