What problem is this PR intended to solve?
Closes #980
Previously Reader#encoding always and only returned the encoding passed to the
constructor. Now, if no encoding is passed to the constructor, then
Reader#encoding will return the encoding detected by the parser.
Have you included adequate test coverage?

Does this change affect the behavior of either the C or the Java implementations?
