Incorrect CHCopyC behavior?

Good day folks. I have an issue with CHCopyC here.

Basically i have this expression:

CHCopyC(gdl_param.stringData.c_str(), reinterpret_cast<char*>(memo_param.value.uStr));

I use it to update the values of properties of elements. However, I got stuck with one particular property called: "Cover Sheet Type".

When I create an element, it is set to a correct value like "A10" or "A09" or else.

However, when I execute the expression above, I receive some nonsense.
Assume:
gdl_param.stringData = "A10";
and
memo_param.value.uStr = {<something>};

By ASCII, "A10" is 65, 49, 48. Hence I expect memo_param.value.uStr to contain {65, 49, 48}. Unfortunately that does not happen and I receive {12609, 49, 48}. I have no idea what "12609" should map to in ASCII, but that is definitely not correct.

The more interesting thing is that I have no problem with other string values. It is only the "Cover Sheet Type" parameter that causes this issue.

Had someone had such issue before and how did you resolve it? I'll be glad for your response! Thank you!

@Emkave

You have posted this in the GDL forum (or it may have been moved there).

Is it actually an API/C++ question?

Barry.

Yes. I am not completely understanding the structure of topics and labels here. Like, I tried to find something very close related to the API and C++, but none were presented in the list
