Manim 动画中的 LaTeX 错误：Unicode 字符问题

It seems like there is an error in your code. The error message suggests that there is an issue with a Unicode character in the LaTeX code.

To resolve this issue, you can try the following steps:

1. Make sure that you have the necessary LaTeX packages installed. Manim relies on LaTeX to render mathematical expressions, so it's important to have the required packages installed on your system. You can refer to the Manim documentation for instructions on installing LaTeX dependencies.

2. Check the Unicode character causing the error. In this case, it seems to be the character '定' in the MathTex equation. Make sure that the character is correctly formatted and supported by LaTeX. You can try removing or replacing the character to see if it resolves the issue.

3. If the issue persists, you can try using raw strings for the MathTex equation. This can help with escaping special characters in the LaTeX code. For example, you can try using MathTex(r'\text{定义} \text{钱} \text{里}') instead of MathTex('\text{定义}', '\text{钱}', '\text{里}').

4. If none of the above solutions work, you can try simplifying the equation or using different LaTeX commands to achieve the desired result.

Remember to recompile your code after making any changes.
