Summary0029069: Samples - handle UNICODE filenames within C++/CLI CSharp sample
DescriptionWhen loading a step file with special characters like ä,Ü,á,... OpenCascade will return with a failure.
Steps To Reproduce1. Rename a step file to for example Inválid.step
2. Try to open it with the STEPCAFControl_Reader::Perform() with the path to the invalid stepfile
3. It always returns false
TagsNo tags attached.

I cannot reproduce the problem with the file named "InválidäÜá.stp": the file gets opened correctly in Import Export sample (both MFC or Qt) in OCCT 7.1.0 (as well as 7.0.0 and 7.2.0). The problem may occur with some other symbols in 7.1.0 -- this is known issue 0027585, fixed in OCCT 7.2.0.

Please check if the problem is resolved in OCCT 7.2.0.

If the problem still persists, please describe more precisely how to reproduce it.

It seems like the error only occurs when you wrap OCCT into a C#-Layer.
Most likely because the string is interpreted as another charset.

If you use ASCII-Charset instaed of Unicode the error stills exists in the 7.1-branch

Here a minimal running example:
#include "TCollection_AsciiString.hxx"

#include "TDocStd_Document.hxx"
#include "XCAFApp_Application.hxx"
#include "STEPCAFControl_Reader.hxx"
#include <iostream>

using namespace std;
using namespace opencascade;
int main(int argc, const char* argv[]) {

    auto filename = "C://temp//Inválid.step"; // <-- If you're using a wchar_t no error will be thrown

    auto format = TCollection_ExtendedString("MDTV-XCAF");
    auto stepDocument = TDocStd_Document(format);
    auto docHandle = handle<TDocStd_Document>(&stepDocument);
    auto app = XCAFApp_Application::GetApplication();
    app->NewDocument(format, docHandle);
    auto stepReader = STEPCAFControl_Reader();
    auto result = stepReader.Perform(filename, docHandle);
    if (result != true)
    {
        cout << "Error.";
        stepReader.Reader().PrintCheckLoad(false,
            IFSelect_PrintCount::IFSelect_GeneralInfo);
    }
    else
    {
        cout << "No Error!";
    }

    return 0;
}

So it seems like that without any additional wrapping-metadata the C#-Wrapper will use the ASCII-Method and fail.

When wrapping to C# is concerned, Unicode strings can be passed correctly to C# level, but the way to do that depends on method used for the wrapping.

So should I consider the issue as resolved and close it?

Oops, I see: it does not work in C# samples in OCCT 7.1 or 7.2
