Sucks but... as of 9/1/16 you may use only English, Chinese, Japanese and Korean characters, as well as numbers and underscores in a username. In the past you were able to use other special font packs but we are presently not supporting this due to performance issues and difficulty searching for users.
We know that special fonts are a way you all like to individualize your profiles and we want to give you all the tools and features to do that. But we also need to keep app performance and stability at the top of our priority list.
We are considering other ideas to help you personalize your user accounts. None of these have been decided on however.
- Releasing inactive usernames more frequently. At present, this occurs infrequently based on a variety of inactivity factors.
- Allowing for "Display Names" which would permit the use of special fonts, characters, emoji, etc. and which might still be unique so nobody could have the same display name as you.
