There was a problem hiding this comment.
Ideas for additional tests:
- Test substrings with length longer than 1.
- Test negative start/end (these appear to work).
- Test start/end that overflows (these appear to not raise an exception).
- Test unicode strings (e.g. character code larger than 127, character code larger than 255).
