Current Behavior

When searching for instances using IDNs the app cannot find it. Also user names with IDNs are not displayed correctly.

Expected Behavior

Support IDN to allow searching for such domain names and display user names with IDNs correctly.

Steps To Reproduce

When signing in search for example for the Mastodon instance „theländ.land“. This Instance exists, but is not found. Workaround: searching for „xn—thelnd-eua.land“.

Environment

All environments.

Anything else?
