[BUG] Ghost character ")" appears in output - similar to #17519 but different character

What's Wrong?

A ghost ) character appears at the end of output lines. This happens intermittently during normal conversation.

Evidence from transcript:

• Claude's actual output (from session transcript): 確かに 🏟️\n\n**GitHub...
• What appeared on screen: 確かに 🏟️ )

The ) character is not in Claude's response - it's a rendering artifact. Verified by comparing the session transcript (.claude/projects/.../[session-id].jsonl) against the displayed output.

What Should Happen?

Output should display exactly what Claude returned, without ghost characters.

Steps to Reproduce

1. Have a conversation in Claude Code (exact trigger unknown)
2. Observe output lines
3. Occasionally, extra characters appear that aren't in the actual response

Note: Intermittent issue - no reliable reproduction steps yet. Happens during normal usage.

• Terminal/Shell: VS Code integrated terminal
• Claude Code Version: 2.1.7

User observed this has happened multiple times during normal usage with no specific trigger.
