+Summary: HttpPostedFile.Filename encoding
+
+Hello,
+ for uploading file I use on client: <form><input type="file"></form>.
+
+In web.config I have
+<globalization requestEncoding="utf-8" responseEncoding="utf-8"	/>
+This should say, what is source encoding for filename uploaded (==
+HttpPostedFile.Filename).
+
+The problem is, that HttpPostedFile.Filename stays UTF-8 encoded and it
+should be to UTF-16 conveted, because .NET type "string" is UTF-16.
+On MS.NET this is converted in UTF-16.
+
+Following method will fix this problem, but I suppose, it should be part of
+System.Web natively:
+
+public static string decodeHttpFileName(string Name) {
+ byte[] sourceBytes = new byte[Name.Length];
+ for (int i=0; i<Name.Length; i++) {				   
+    sourceBytes[i]= (byte)Name[i];
+ }
+		
+// Convert utf8 -> unicode
+byte[] destBytes = Encoding.Convert(Encoding.UTF8, Encoding.Unicode,
+sourceBytes);
+            
+// Convert the new byte[] into a char[] and then into a string.
+char[] destChars = new char[Encoding.Unicode.GetCharCount(destBytes, 0,
+destBytes.Length)];
+Encoding.Unicode.GetChars(destBytes, 0, destBytes.Length, destChars, 0);
+string destString = new string(destChars);
+	     
+return destString;
+}
