That's the PHP definition of "bulletproof" - whatever happens, no matter how bad, just keep right on going. If you really want some way to write "just anything" to your file, I recommend not using JSON - instead, write out the repr of your data structure. That'll give a decent result for bytes, str, all forms of numbers, and pretty much any collection, and it won't break if given something that can't safely be represented.
