Bug: Broken Chinese Characters Appearing in Antigravity UI (Encoding Issue)

I’m encountering a strange issue while using Antigravity inside the Google AI Developers environment.

During task execution, the progress/thought logs are filled with random Chinese characters such as and numbers like 1656 repeatedly, which makes the output unreadable.

What I expected

The thought/progress logs should display clean English text explaining the steps of the task execution.

What actually happens

The logs contain repeated broken characters (Chinese symbols + numbers) that look like corrupted text.

Example pattern appearing repeatedly:

破 1656 破 1656 破 1656

This occurs multiple times between the normal English log messages.

Steps to reproduce

  1. Open Google AI Developers → Antigravity environment

  2. Run a task that generates progress/thought logs

  3. Observe the output panel

Additional details

  • Browser: Chrome

  • OS: Windows

  • Occurs consistently during task execution logs

  • Screenshots attached below

Impact

Because the logs contain corrupted characters, it becomes difficult to debug tasks or understand what the agent is doing internally.

Would appreciate it if the team could investigate whether this is a logging/encoding bug in Antigravity.

Thanks.
