import { strgetchar } from "https://deno.land/x/denops_std@v4.1.4/function/mod.ts";
Get a Number corresponding to the character at {index} in {str}. This uses a zero-based character index, not a byte index. Composing characters are considered separate characters here. Use |nr2char()| to convert the Number to a String. Returns -1 if {index} is invalid. Also see |strcharpart()| and |strchars()|. Can also be used as a |method|: GetText()->strgetchar(5)
