import { screenchars } from "https://deno.land/x/denops_std@v3.6.0/function/vim/mod.ts";
The result is a |List| of Numbers. The first number is the same as what |screenchar()| returns. Further numbers are composing characters on top of the base character. This is mainly to be used for testing. Returns an empty List when row or col is out of range. Can also be used as a |method|: GetRow()->screenchars(col)
