Bug Report: Character Encoding Issue in Cursor CLI

[Kevin_Fujiang]

Where does the bug appear (feature/product)?

Cursor CLI

Describe the Bug

When pasting a paragraph of Chinese text containing approximately 100 Chinese characters into the CLI, there is a high probability that character corruption (��) will occur.

Steps to Reproduce

1. Copy the following text to your clipboard: 「对公付款申请流程」 必须有发票, 这个流程, 就只能是“充值” 行为的流程. 之前里面有“冲销”的逻辑, 就没有用了.
2. Open cursor-agent in the terminal and paste the clipboard content.
3. One or more garbled characters (�) will appear in the cursor-agent output, for example:
   「对公付款申请流程」 必须有发票, 这个流��, 就只能是“充值” 行为的流程. 之前里面有“冲销”的逻辑, 就没有用了

No - Cursor works, but with this issue

Hi @Kevin_Fujiang!

I’ve tried to reproduce this but haven’t been able to.

Could you run agent upgrade to make sure you’re on the latest version of the CLI? It looks like you might be a few versions behind (the latest stable in 2026.08.31)

[Kevin_Fujiang]

After executing agent upgrade, execute the agent again and paste the content into the CLI. The issue still persists.

MacOS: 26.6.2 (25G83)

[Kevin_Fujiang]

Pasting content from TextEdit or Sublime Text into the agent CLI often causes random garbled characters in unpredictable positions.

Does it reproduce in the regular macOS terminal (not Ghostty)?

[Kevin_Fujiang]

It works fine in the Apple Terminal, so it should be a bug in Ghostty.
