import { strcharlen } from "https://deno.land/x/denops_std@v4.1.4/function/vim/mod.ts";
The result is a Number, which is the number of characters in String {string}. Composing characters are ignored. |strchars()| can count the number of characters, counting composing characters separately. Returns 0 if {string} is empty or on error. Also see |strlen()|, |strdisplaywidth()| and |strwidth()|. Can also be used as a |method|: GetText()->strcharlen()
