How to echo special characters

Question

I am using the Steam OpenID API to retrieve usernames. The problem is some users have names like this:

█Ỏ͖็✪3░⠀็Ỏ͖͈̞̩͎̻̫̫̜͉̠̫͕█

but when the username is inputed into the webpage this is what the username looks like:

█Ỏ͖็✪sw3🔘tâ–‘â €à¹‡á»ŽÍ–ÍˆÌžÌ©ÍŽÌ»Ì«Ì«ÌœÍ‰Ì Ì«Í•â–ˆ

I couldn't find a solution to this problem, but if someone could manage to find the solution, please link it in the answer.
