How are some people able to use special characters in their names?

Won’t let copy and paste it when you try change name

I just did this one and it worked just fine.

As I said some symbols do not work.

Even if aome symbols work, why is that the name field has no paste option.

Copy it here, then in game, click where you would enter the name, long press with your finger until paste comes up.

I have tried several times and it does not come up even long pressing. I have tried over and over again

I’m having the same issue

I downloaded the ‘Font’ app and it helped me

Which one there is many

For those that can't "copy and paste" you need to copy, then manually pull up your clipboard from your key board and select it that way. That's how I did it
