In fact, it is correct up to the character offset.

Thanks for the bug report, the precision on the character offsets has been a bit of a problem for this test suite for a while, and one I've meant to address.

I do most of my development on macOS, where the file is a unix-style text file with single-character line-endings. The Windows (or DOS) style file endings which are two-character cause the count to be slightly different.

I need to come up with a way to make this a bit more permissive, but I've not done it yet. Thanks for the bug report!
