Kimi CLI Diff Rendering Bug: Markdown bold ** shown as NN, Chinese characters garbled

Environment

• kimi version: 1.30.0
• OS: macOS
• Shell: Terminal (likely default macOS Terminal or iTerm2)
• Locale: zh_CN.UTF-8

Description

When Kimi CLI renders a file diff (e.g. after WriteFile output), the diff view incorrectly renders certain characters:

1. Markdown bold syntax ** is displayed as NN (e.g. **结论** → NN结论NN).
2. Some Chinese characters are garbled or replaced with wrong glyphs in the diff frame.

The actual file content on disk is correct UTF-8 — this is purely a terminal UI rendering bug in the diff display layer.

Screenshot

See attached screenshot: Screenshot 2026-04-04 at 14.28.04.png

In the screenshot, lines like:

+ **结论**: 外部浏览器/App 到 Nginx **只支持 HTTPS**

are rendered as:

+ NN结论NN: 外部浏览器/App 到 Nginx NN只支持 HTTPSNN

Additionally, some Chinese characters inside the diff frame appear corrupted (e.g. 部分 ** 包裹的文字或表格内的中文字符显示异常).

Reproduction Steps

1. Run kimi CLI in a project directory.
2. Ask the agent to create or overwrite a Markdown file containing Chinese text and **bold** syntax.
3. Observe the diff preview that appears after WriteFile.
4. Notice ** → NN and occasional Chinese character corruption.

Expected Behavior

Diff preview should render the exact file content: ** should remain **, and Chinese characters should not be garbled.

Actual Behavior

Diff preview mangles ** into NN and occasionally corrupts CJK characters.

Impact

• Makes it hard to verify generated content before accepting changes.
• Occurs intermittently but frequently enough to be disruptive over several days.

Additional Context

• The bug appears in the diff/frame rendering, not in the actual file write.
• Possibly related to syntax highlighting or ANSI escape sequence processing in the diff viewer.
