import { screenstring } from "https://deno.land/x/denops_std@v3.11.1/function/mod.ts";
The result is a String that contains the base character and any composing characters at position [row, col] on the screen. This is like |screenchars()| but returning a String with the characters. This is mainly to be used for testing. Returns an empty String when row or col is out of range. Can also be used as a |method|: GetRow()->screenstring(col)
