Feral Heart

Hi, I recently became a member and as you can see I have a hyphen ( - ) in my username. However, when I try to log into the game on mac, the regular key for hyphen turns it into a + sign instead? I've tried every key on my computer with different variations and nothing seems to work, I even tried to copy and paste but it didn't work either.. Does anyone know how to solve this or do I have to create a new account? :/
