Memory in biological brains is not a linear series of bits, or 
characters. How we do associate things is still mostly a puzzle.

Read about holographic memory.

No. A unicode string is a sequence of abstract characters or codepoints. 
They must be encoded somehow to map them to linear byte memory. There 
are still (too) many encodings in use. Most cannot encode *all* unicode 
characters.

CPython is unusual in using one of three different encodings for 
internal unicode strings.

This is excellent advice. One of the *features* of Python is that one 
*can* forget about addresses. One of the *problems* of C is that many 
people *do* forget about memory locations, while virus writers study 
them carefully.
