FWIW this is fixed in the dev version of stringr which uses stringi
under the hood:
> stringr::str_split_fixed('ab','',2)
[,1] [,2]
[1,] "a" "b"
> stringr::str_split_fixed('ab','',3)
[,1] [,2] [,3]
[1,] "a" "b" ""

Dear David,
str_split_fixed calls str_locate_all, which gives
str_locate_all("ab", "")
## [[1]]
## start end
## [1,] 1 0
## [2,] 2 1

in your example, since "" is a character of length 1. substring() is
probably more intuitive to get your expected result:
substring("ab", 1:2
2 matches
