Shell details panel renders Chinese characters as blank on Windows

Environment

• OS: Windows 11
• Terminal: Windows Terminal
• Claude Code: Latest version

Description

When running commands that output Chinese characters, the Shell details panel renders some lines as blank/empty, even though the actual output is correct.

Steps to Reproduce

1. Run any command that outputs Chinese text with special punctuation (e.g. characters like 【】（）、。)
2. Open Shell details panel
3. Some lines appear blank

Expected Behavior

All output lines should be visible in the Shell details panel.

Actual Behavior

• Shell details panel: Some lines containing Chinese punctuation are blank
• TaskOutput tool: Can read the content correctly

Workaround

Using TaskOutput tool to read the output file works correctly, confirming the issue is with UI rendering, not the actual output.

Additional Context

Setting NO_COLOR=1 does not fully resolve the issue - basic Chinese text displays but lines with special Chinese punctuation still render as blank.
