du shows empty for dotnet string content in WinDbg?

Question

I am analyzing a memory dump file from a dotnet core process.

0:000> !DumpObj /d 000002037237a720
Name:        System.String
MethodTable: 00007ffee91dd698
EEClass:     00007ffee91b9d60
Tracked Type: false
Size:        809656(0xc5ab8) bytes
File:        C:\WebSites\System.Private.CoreLib.dll
String:      
Fields:
              MT    Field   Offset                 Type VT     Attr            Value Name
00007ffee91c9480  40002f2        8         System.Int32  1 instance           404817 _stringLength
00007ffee912ea10  40002f3        c          System.Char  1 instance               7b _firstChar
00007ffee91dd698  40002f1       e8        System.String  0   static 000001fd510413a0 Empty

I want to see the content of this string.

I tried the following commands and they dont work. It shows empty string but surely it is not empty.

0:000> du 00007ffee912ea10
00007ffe`e912ea10  ""
0:000> d 00007ffee912ea10
00007ffe`e912ea10  ""
0:000> du 00007ffee912ea10 00007ffee912eB10 
00007ffe`e912ea10  ""

Did I make some mistake?
