// if I get a Cstring and then pass to std::string
// and then if I put the std::string.c_str() in the <filepath> the
//fz_open_document.

//std::string filepath(CW2A(l_SampleDlg.GetPathName()));
fz_document *_doc = fz_open_document(_ctx, filepath); /*== NULL*/

// simply dont open and return null
// ---- it necessary convert the cstring to const char*
//like this
/*
CString TempCs_Cs = l_SampleDlg.GetPathName();
const char* filepath;
CT2A ascii(TempCs_Cs, CP_UTF8);
TRACE(_T("UTF8: %S\n"), ascii.m_psz);
filepath = ascii;

fz_document *_doc = fz_open_document(_ctx, filepath); /* == Return success*/

i dont not know is this supposed to happened or if I miss something on the
document , but maybe this type of convertion is corrupting the const string for
some reason.

MuPDF is written in C, not C++ it looks to me like you are passing a C++ string
object to a function which expects a C string.

That's not going to work.

If you want to use MuPDF with C++ you are going to have to write some kind of
interface, or at least not try and pass C++ objects to the C interface.
