+Bug#: 77482
+Product: Mono: Class Libraries
+Version: 1.1
+OS Details: 
+Status: NEW   
+Priority: Normal
+Component: System
+AssignedTo: mono-bugs at ximian.com

+TargetMilestone: ---
+Summary: DirectoryInfo.GetFiles() failes with international characters
+I've written a simple program to illustrate the problem.
+using System;
+using System.IO;
+public class FileTest
+	public static void Main (string [] args)
+	{
+		foreach(string dir in args)
+		{
+			Console.Write(dir);
+			DirectoryInfo dinfo = new DirectoryInfo (dir);
+			if(dinfo.Exists)
+			{
+				Console.WriteLine(" exists.");
+				foreach(FileInfo finfo in dinfo.GetFiles())
+				{
+					Console.WriteLine("\t" + finfo.Name);
+				}
+			}
+			else
+			{
+				Console.WriteLine(" does not exist.");
+			}
+		}
+	}
+When I run this program it throws an exception if a filename contains
+international characters encoded with something other than utf-8. Example:
+kweek filetest% MONO_EXTERNAL_ENCODINGS="iso-8859-1" mono --debug
+FileTest.exe birch
+birch does not exist.
+kweek filetest% mkdir birch
+kweek filetest% MONO_EXTERNAL_ENCODINGS="iso-8859-1" mono --debug
+FileTest.exe birch
+birch exists.
+kweek filetest% MONO_EXTERNAL_ENCODINGS="iso-8859-1" mono --debug
+FileTest.exe björk
+björk does not exist.
+kweek filetest% mkdir björk
+kweek filetest% MONO_EXTERNAL_ENCODINGS="iso-8859-1" mono --debug
+FileTest.exe björk
+björk exists.
+Unhandled Exception: System.IO.FileNotFoundException: Could not find file
+"/home/stonebone/tmp/filetest/björk" : /home/stonebone/tmp/filetest/björk
+in [0x00166] (at
+System.IO.Directory:GetFileSystemEntries (System.String path, System.String
+pattern, FileAttributes mask, FileAttributes attrs)
+in [0x00005] (at
+System.IO.Directory:GetFiles (System.String path, System.String pattern)
+in [0x00007] (at
+System.IO.DirectoryInfo:GetFiles (System.String pattern)
+in [0x00006] (at
+System.IO.DirectoryInfo:GetFiles ()

+in [0x00037] (at /home/stonebone/tmp/filetest/FileTest.cs:18) FileTest:Main
+(System.String[] args)
+Notice that Exists returns true, yet GetFiles() it throws
