5 UTF-8 characters span multiple bytes, and it is easy to inadvertently confuse character
6 counts and string indices. This may lead to panics, and should warrant some test cases
7 containing wide UTF-8 characters. This lint is most useful in code that should avoid
11 Probably lots of false positives. If an index comes from a known valid position (e.g.
12 obtained via `char_indices` over the same string), it is totally OK.
