Hi, I am working with the Keycloak OIDC feature, and needed some clarification regarding the character set it supports: 1. I have a requirement to use utf-8 characters (multi byte) in the Username field which seems to work fine while setting the user name and I can login to Keycloak. But it seems there are other related issues while generating / encoding the tokens. Sometimes (some characters) it works fine but for some multibye characters it throws { "error": "invalid_grant", "error_description": "Code not valid" } while trying to get the Tokens using the authorization code. Can someone tell me if Keycloak actually supports utf-8 character set in Username and other fields and also in Custom user attributes? It would be of great help if anybody can share some information.
