@brief CharStream that reads data from a file-like object.

This is a char buffer stream that is loaded from a file like object all at once when you construct the object.

All input is consumed from the file, but it is not closed.

@param file A file-like object holding your input. Only the read()
   method must be implemented.

@param encoding If you set the optional encoding argument, then the
   data will be decoded on the fly.
