There's a general expectation that indexing will be O(1) because all the builtin containers that support that syntax use it for O(1) lookup operations.
Depending on your definition of built in, there is at least one standard library container that does not - collections.deque.
Given the specialized kinds of application this Python implementation is targetted at, it seems UTF-8 is ideal considering the huge memory savings resulting from the compressed representation, and the reduced likelihood of there being any real need for serious text processing on the device.
Right - I wasn't clear that I think storing text internally as UTF-8 sounds fine for MicroPython. Anything where the O(N) nature of indexing by code point matters probably won't be run in that environment anyway.
