PowerShell Help

I am trying to pass args from powershell to js,and using iconv to decode the string,but afterward , i need to pass it back,but when passing back it become gibberish,so how can i decode it in powershell?

const { exec} = require('node:child_process') 
const os = require("os");
const iconv = require('iconv-lite');
const encoding = os.platform() == 'win32' ? 'cp936' : 'utf-8';

const binaryEncoding = 'binary';
// 执行命令并获取结果
const { argv } = require('node:process');



argv.forEach((args) => {
    const runExec = (powershell) => {   
        return new Promise((resolve, reject) => {
            exec(powershell, { encoding: binaryEncoding }, function(error, stdout, stderr) {
                if (error) {
                    reject(iconv.decode(new Buffer.from(error.message, binaryEncoding), encoding));
                } else {
                    resolve(iconv.decode(new Buffer.from(stdout, binaryEncoding), encoding));
                }
            });
        })
    }
    var url = process.argv.slice(2);
    return new Promise((resolve, reject) => {
    runExec(`"POWERSHELL" C:\\Users\\Administrator\\dre\\dre-main\\crawl1.ps1 ${url}`,{ encodingback: binaryEncoding }).then(res => {
    
        
        
    const jsdom = require("jsdom");
    const dom = new jsdom.JSDOM(res)
console.log(dom.window.document.title)
    }).catch(err => {
        console.log('执行失败', err);
    })})
    
});

            [CmdletBinding()]
            param (
