Error message from c++ compiler is messy when build mex file.

I'm building some mex files from c++ source files using Microsoft visual studio 2017 as the compiler. But the error message is not readable. I think it's encoding problem, but I don't know how to solve it. Can someone help me?

Hi Jiangfeng Liu,

It appears to me that you are facing difficulty in building mex files from c++ source files using Microsoft visual studio 2017 as the compiler. The error message you are seeing is likely due to a mismatch between the character encoding used by Visual Studio's output and the encoding expected by MATLAB's command window or the console where you are viewing the message. Here are few ways to resolve the encoding issue:

• Change Console Code Page:

1. Open a Command Prompt window.

2. Before running MATLAB, change the code page to UTF-8 by typing “chcp 65001”.

3. Start MATLAB from this Command Prompt window and try building the MEX file again.

• Change MATLAB's Default Character Encoding: In MATLAB, you can change the default character set to UTF-8 by running the following command:

        feature('DefaultCharacterSet', 'UTF-8');

After setting this, try to compile the MEX file again.

I hope this helps.
