After copying Chinese, Japanese, or Korean from the terminal, pasting the content into the terminal may result in garbled text.

### Describe the bug

When I copy Chinese, Japanese, or Korean from the terminal, there is a chance that pasting the content directly into the terminal will result in garbled text.

The scope of this bug includes both the model's own responses and the content in the input box.

Copying Chinese character/Kanji from the input box and then pasting it almost 100% results in garbled text.

Pasting the text outside the terminal does not cause any issues, and text copied from outside the terminal almost never encounters this problem.
