WinRT No mapping for the Unicode character exists in the target multi-byte code page

Question

I am trying to read a file in my Windows 8 Store App. Here is a fragment of code I use to achieve this:

        if(file != null)
        {
            var st         


        

Answer 1

Try this instead of string text = dataReader.ReadString(numbytes):

dataReader.ReadBytes(stream);
string text = Convert.ToBase64String(stream);
