keycloak: google login character encoding error

Question

We are using keycloak standalone server to authenticate our users. Social IDPs: google and facebook login work perfectly, except the following mistake:

If on your google account first and last names are written with non-ascii characters, keycloak doesn't read them properly.

For instance: Name on the google account is Собиров Валижон. What I get on keycloak is РЎРѕР±РёСЂРѕРІ Валижон

Steps to reproduce the issue:

• add test realm and client
• add google identity provider settings
• login with google user who has non-ascii chars in first or lastname (in my case Собиров Валижон)
• see keycloak test realms user database

It would be appreciated if someone could solve the issue.

Answer 1

The only solution I could find was to put default encoding in JVM.

Add default encoding to standalone.conf

JAVA_OPTS="$JAVA_OTPS -Dfile.encoding=UTF8"
