Passing file path with specific Chinese characters makes .NET classes (e.g. XPathDocument) generate System.IO.DirectoryNotFoundException

Reported by Rafał Denkiewicz Apr 26 at 02:02 PM .net

Steps to reproduce:

1. Create folder with name '专丌　颕‎兀专丌　颕‎兀专丌　颕'

2. Put some file into this folder

3. Run code and point the file

var ofd = new OpenFileDialog();
if( ofd.ShowDialog() == DialogResult.OK)
{
 var x = new XPathDocument(ofd.FileName);
}

As the result exception is thrown: System.IO.DirectoryNotFoundException

Please make note that other classes that operate on file paths are also affected.

There are binary differences when comparing the path from the exception message with the file path processed on .NET Framework 2.0.

The bug seems to be introduced in .NET Framework 4.5 (still exists in the newest version 4.7.1)

Reproduced on both Windows 10 and Windows 7 (English)
