This is a question for your server side database. You need some sort of solution that can query the database. If by 'encoded' you mean something like the Maps encodeding system, you are probably going to have to decode the data to run spatial queries on it.
Perhaps you need to run a batch process, to decode the lines, and store a bounding rectangle in the database. It trival then to find points in those rectangles. But this all depends on your database, and its capablities.
