A found a weird looking letter on Fortnite and I want to friend the dude that has it in his name. I will put two reference images in the topic and in Calibri i'm pretty sure. I just need help naming the character.

The other image is too small so here is a bigger version

Without knowing the context it could be anything. What is showing around that? Are there other letters? Of what script or language?

Cyrillic has a letter like that http://graphemica.com/Ф

Greek as has a letter like that http://graphemica.com/Φ

Just to name two options that first come to mind. 

Thank you! That's all I need. I will try both and if it doesn't work. There is English around these letters but it is in a username. An English username.
