Answer 1

It’s just a mass of combining marks. That alone is like 170 Combining Marks. You can do all sorts of weird rendering effects just by using a ton of combining marks together. But in this case just U+0489 COMBINING CYRILLIC MILLIONS SIGN is used.

Combining marks are not stand alone characters by themselves, but modify the previous base letter. For example a, a combining diaeresis ¨ renders as ä instead of a¨. Put more combining marks in there, and they all have to somehow render with the base character a, causing interesting rendering effect.

Code in the jsfiddle (SO didn’t allow me to post otherwise):

var l = 1000;

var str = ":"

while(l--) {
    str += String.fromCharCode(0x300 + Math.floor((Math.random() * 0x20)))
}

document.write(str);
