When trying to use TCST package for matlab getting this error in MATLAb 2024a "Caught "std::exception" Exception message is: Invalid character code sequence detected."

I am trying to use TCSTInterface to run and optimize some structures in CST MWS. When I try to open and run any CST file from MATLAB 2024a, the program throws me the error:

Caught "std::exception" Exception message is:

Invalid character code sequence detected.

This error is not observed on an older matlab version.

Kindly help.

Hi Aditya

The presence of non-English characters in a file path is usually indicated by the warning "Invalid character code sequence detected".

You might want to look for non-English characters along the following possible paths:

• Tempdir
• Prefdir
• Matlabroot
• !hostname

You might be able to fix this mistake by changing any non-English characters in these pathways to regular English ones.

I hope this helps.

Hi Aditya,

Thank you for your suggestion. I’ve checked all the paths you mentioned, including tempdir, prefdir, matlabroot, and the hostname, and I can confirm that none of them contain any non-English characters. Despite this, I’m still encountering the same issue with the error message: "Invalid character code sequence detected."

Would you have any other recommendations or insights on how to resolve this issue?

Thank you in advance for your help.
