Cursor selection inconsistent across editors

[frelodev]

If a block of text is selected from the left to the right it sends the event properly.
Otherwise if it's selected from the right to the left it goes off by one to the right

Did some testing on multiple clients with @alemidev and @frelodev. This may not even be in the library but an unfortunate combination of issues spread across multiple editors, as it seems wildly inconsistent across different editors but always the same within the same editor.

I think this may be due to multi-byte characters and some other bugs we solved, is this still relevant?
