Yes, slicing counts. What matters here is the potential impact of internally representing strings as UTF-8 streams; when you ask for the Nth character, it would have to scan from either the beginning or end (more likely beginning) of the string and count, instead of doing what CPython 3.3+ does and simply look up the header to find out the kind, bit-shift the index by one less than that, and use that as a memory location.
