Problem with some characters in wxURI

[jimmiejams]

Hi,

We have a GUI program that had been running on wxWidgets-2.8.12 on Mac without a problem, but now that we've moved to 3.0.3 we're hitting problems opening ZIP files with Brazillian Portgueuse characters in the filename. An example would be something like this:

Code: Select all

wxString filename = ".../MoldurasPadrão1.mpk";
wxString base = filename + "#zip:);
wxString path = "element.txt";
wxFileSystem fs;
FSFile *fsf = fs.OpenFile (base + path);

This then raises an assert in wxUniChar::ToHi8bit() saying "character cannot be converted to single byte". I've narrowed it down to just this example:

Code: Select all

#include <wx/app.h>
#include <wx/string.h>
#include <wx/uri.h>

class MyApp : public wxApp {
    bool OnInit (void) {
        wxString path = wxURI::Unescape  ("MoldurasPadrão1.mpk");
        return false;
    }
};

wxIMPLEMENT_APP (MyApp);

Our wxWidgets is compiled using the following configure options:

Code: Select all

configure --with-macosx-version-min=10.9 --enable-compat26 --disable-shared --enable-stl --enable-debug --with-flavour=debug

I can provide the full output from configure if it helps. The compiler is clang from Xcode 9.4.1 on macOS 10.13.6.

The strange this is, if I just compile and run this, I don't get an assert, which makes me think maybe we're not intialising something wxWidgets needs in the GUI version.

Code: Select all

#include <wx/string.h>
#include <wx/uri.h>

int main (void)
{
    wxString path = wxURI::Unescape  ("MoldurasPadrão1.mpk");
    return 0;
}

Can anyone reproduce this problem on macOS?

Hi,
Did you try to recompile the wxWidgets with "--enable-unicode"?
I don't know if this will be set on Mac with non-default configure...

Thank you.

Hi,

Thanks, I gave that a go just now, but no improvement I'm afraid. I'll try a more stock compilation of wxWidgets next, and see if that makes any difference.

Hi,
In you sample can you step through in the Unescape() method and see what happens?

Thank you.

wxURI::Unescape("MoldurasPadrão1.mpk");

By my definition this is not a valid URI, as it contains a non-ascii character. (Although it works under Windows).

How is that related to the ZIP problem? Is wxURI::Unescape used in the ZIP processing somewhere?
