Rename a PDF file to something like this and it will not load:

新建文本文档.pdf

Exception: Unexpected error code.
(Patagames.Pdf.Net.Exceptions.PdfiumException)

Can you look at this?

Can you please confirm this issue and, if so, provide a fix soon in the next update?

With the latest Pdfium.Net SDK (2.15.1.2595), a blank VS 2010 WinForms .NET Framework 4 project, and only a PdfViewer on the form:

pdfViewer1.LoadDocument("c:\\test\\pdf\\新建文本.pdf");

Results in the exception below. If I change the name 新建文本.pdf to test.pdf and load it, it works fine. I believe any Chinese character in the path may cause it to fail. It's possible that characters from other languages also have this issue.

Patagames.Pdf.Net.Exceptions.PdfiumException was unhandled

Thanks: 10 times

Unfortunately Pdfium uses non-unicode version of CreateFile function so it cannot open such files directly.
I can suggest a following workaround:

Code:

var stream = System.IO.File.OpenRead(@"d:\0\新建文本文档.pdf");
var doc = PdfDocument.Load(stream);
//....
doc.Dispose();
//Please note you should close the stream strongly after doc.Dicpose() was called.
stream.Close();


Please note you should close the stream strongly after doc.Dicpose() was called.

Thanks, the Stream argument works for now. It would still be nice if this is something that could be handled internally by Pdfium.Net SDK in a future update, since there's an assumption of unicode support for file path parameters.

I noticed that saving PDFs doesn't have the same issue. For example, this works: doc.Save("新建文本.pdf", Patagames.Pdf.Enums.SaveFlags.Incremental);
