Open an output PDF file with a Unicode file name.
// Windows only XpdfSpliceOutputHandle xpdfSpliceOpenOutputW(const wchar_t *pdfFileName, double pdfVersion)
This function opens an output PDF file, pdfFileName, from disk, and constructs a handle.

This function is identical to xpdfSpliceOpenOutput, except that the file name is Unicode (whcar_t* instead of char*).

The xpdfSpliceOpenOutputW function returns an XpdfSpliceOutputHandle if successful, and otherwise returns NULL.

The PDF version in the output file will be set to pdfVersion. XpdfSplice does not check that the content conforms to the specified version. Typically, it should be set to the highest version used in any of your input files.

This function is only available on Windows.

XpdfSpliceOutputHandle out; out = xpdfSpliceOpenOutput("c:/test/newfile.pdf", 1.6); if (!out) { /* handle the error */ }
