1. Login to your shop as admin
2. go to your account, choose "Show or change my account information"
3. you get forwarded to the backend, choose a new e-mail adress for logging in, the new e-mail adress must contain an umlaut, save
4. don't log out!
5. open a new session, try to login with the new e-mail --> a message appears, login with umlaut in e-mail adress not possible
6. in the first session, change your e-mail adress back to 'normal', save

expected:

• you shouldn't be able to create e-mail adresses with umlaut anywhere in the shop

actual:

• it is possible to create an e-mail adress with umlaut, which can't be used for logging in
