Making a drop of storing skipBuffer in Reader sonds another solution that acceptable to me, as it makes the handling strategy same in Reader and InputStream classes.

I don't think use frequency can influence this. In other words, I still think, if there be no special acceptable reason, we shall make the skipBuffer handle strategy same in Reader and InputStream classes.
