UTF-32 is currently not part of Silverlight, so you have to find a way around the limitation. I think you should stop a moment and think exactly why you need to read UTF32-encoded text.
If you are reading such text from a database or a file on the server, I would perform the conversion server-side (if possible I would convert everything to UTF-8 and get rid of the UTF-32 data in one shot).
If you are parsing a user-provided file on the client side, I would detect the UTF-32 encoding and gently tell the user that the file encoding is not supported. UTF32 is pretty rare nowadays, so I guess it should not be a very common case (but I could be wrong not knowing your exact situation).
In order to detect the file encoding you have to look at the first few bytes (byte order mark) -more information here, if they are not present the task becomes much harder and involves some kind of heuristics based on character frequency.
