How do you express that you're laughing when you are texting? I had this doubt when I was talking to someone who isn't from the same country as I am and I was writing "haha" but I didn't know if he would understand it. In Brazil, for example, we use a lot of things to express laugh, like "kkkkk" "hauahauhaua" "hahahaha" or just some random letters after something funny like <something funny> poksospsksok and that's a laugh
