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

1、XPathDocument internally uses Uri’s LocalPath property.

2、String (专丌　颕‎兀专丌　颕‎兀专丌　颕) has two invisible characters.

3、Result of LocalPath omits those two invisible characters. This causes the path to be different from the original path.

You can verify it by those code:

var fileName = "D:\\专丌　颕‎兀专丌　颕‎兀专丌　颕";

var uri = new Uri(fileName); var equal = uri.LocalPath == fileName;

var arr1 = uri.LocalPath.ToArray(); var arr2 = fileName.ToArray();<br>

Personally think it's still a bug, but the bug is in the Uri class instead of XPathDocument.

Forgive my poor English!
