Message decoding issue in AKHQ with Confluent Schema Registry topics: unreadable characters

[fmessina92]

Hello,
I am experiencing an issue where AKHQ does not properly decode messages coming from Kafka topics managed with Confluent Schema Registry. Kafka applications can read the messages correctly, but AKHQ displays strange or unreadable characters (e.g., � or red squares). This is often because the messages contain binary or serialized data formats that are not valid UTF-8, causing rendering issues in AKHQ. I’m looking for guidance on how to configure or fix this problem to properly display the data in AKHQ.
Thanks everyone in advance

@fmessina92 can you give us an example of schema / message causing this + screeshot of how AKHQ renders it ?

Apologies for the masking, sensitive data has been hidden. Some information is still readable, while other parts remain obscured with scrambled characters.
