Thanks for the free code :)
I think that will be the way to go in my case, since most input will be
ascii and moving the cursor will be quite rare
If I was expecting a decent amount of non-ascii input, I would use the
bitvector approach described by Thomas Oltmann. 1bit per byte overhead
should be fine for most use-cases.
I think it is very good too, the only problem is the overhead of having
to preprocess everything
Thank you a lot for helping!
