电脑的语言是中文，使用Simulink搭建的模型，生成代码时，代码文件的编码都为中文编码，我想设置文件编码为UTF8，应该如何设置。

Hi @leifeng song
You can specify the encoding used for generated code by using the slCharacterEncoding function in MATLAB.
For example, run the following command before code generation:
>> slCharacterEncoding('UTF-8');
After running this, the generated C and H files will be encoded in UTF-8.
Please note that this setting applies for the current MATLAB session.

Thank you，but it does not work. the function "slCharacterEncoding" was description in slCharacterEncoding - 指定要在从 Simulink 模型生成的代码中使用的编码 - MATLAB.
I try it,the result is ,once there is some chinese comment words in the generator code , the code file encoding turns GB2312,otherwise ,the encoding is UTF-8.
