Print raw field data
It is possible to do it without coding from the admin area.(Disclaimer: a bit hacky).

Go to the "admin/config/content/formats" area and disable all the filter formats except "Plain Text". 

Go to your content type display settings tab and change the format in the dropdown to "Default" and save the settings.

If you view your node now, you will be able to see its raw content form without all the sanitation.
