I'm in favor of this, but have two concerns:

1. I don't like that a "Parser" option is changing the output of the encoder. Given we don't have a way to set encoding options, I think we can live with this for now.
2. This change must add unit tests, otherwise it will be too easy to break in the future.

Thank you @jhillyerd
I know what you mean, I'm not a fan either. I've tested to change the behavior of the Encode function, but without luck.
I've added a simple test that will show the diff with and without the option.

Looks good, just a couple small changes, thanks.
