Unfortunately in the current Python3 email package (email5), this is no longer true. You have to decode everything *first* in order to pass it through email (which presents a few problems when dealing with 8bit data, as has been mentioned here before). eamil6 intends to fix this, and once again allow you to decode to text only the bits you actually need to access and manipulate. -- R.
