Description

The Hermes CLI/TUI has significant rendering issues when handling Chinese characters:

• Character Overlap/Misalignment: When typing Chinese characters, the input box layout breaks and the cursor position becomes offset.
• Deletion Bug: Pressing backspace to delete Chinese characters does not correctly clear the visual space, leading to 'ghost' characters or incorrect screen updates.
• Rendering Lag: There is noticeable visual corruption when mixing English and Chinese in the same input line.

This makes using Hermes in a native Chinese terminal environment very difficult.

Steps to Reproduce

1. Run hermes in a terminal.
2. Type a string of Chinese characters (e.g., 你好测试).
3. Try to backspace to delete them.
4. Observe the visual corruption in the input box.

Environment

• OS: Linux (CLI)
• Hermes Version: 0.8.0
• Terminal: UTF-8 compatible
