arabic issue when connect with opencode

I'm having a problem with the Arabic language when I link Buzz to OpenCode. The agent responds in Arabic within the activity, but the interface doesn't allow Arabic encoding. However, when I interact with Buzz, the Arabic language appears normally.

Start by reproducing the issue while connecting Buzz to OpenCode and sending Arabic text. Compare Arabic rendering in the activity interface with Arabic interactions in Buzz, using the attached screenshot as the expected context. Done means Arabic responses from the connected agent render correctly in the activity.
