Before you start
Prepare more than one version of your new name. A plain backup is useful if a symbol or Unicode character is not accepted by your current client.
Change the nickname
- Open the game and go to your profile.
- Select the edit control beside your current nickname.
- Paste or enter your new name.
- Review every character and the displayed cost or required item.
- Confirm only when the preview is correct.
If the name is rejected
Check the length shown in-game, remove uncommon symbols, and try a simpler Unicode style. Requirements can change, so the game interface is the final source of truth.
