What's that character before W in Whatsapp icon?

iOS and iPadOS

I generally put my apps in different folders and use Braille Screen Input to open them. While trying to open Whatsapp with this method, I found it just didn't work! On doing a check it turned out that there's a character before W but VoiceOver is not anouncing that character. Could someone help me with that? Not a very big deal but just for curiosity and maybe will make me learn something? T
