Note also that this is buggy:

```julia
julia> s = "α.jl"
"α.jl"

julia> s[begin:end-3]
ERROR: StringIndexError: invalid index [2], valid nearby indices [1]=>'α', [3]=>'.'

```

(It’s really tempting to write this, which is a key motivation for a [`StringIndex` type](https://discourse.julialang.org/t/stringindex-idea-julia-2-0/107185).)
