(javascript) 或 (windows 中的 nodejs) iconv 从 utf-8 到 iso

Question

我正在使用 nodejs http.get 方法将数据发布到 php

但是 php 的字符集不是 UTF-8，它是 ISO-8859-9（土耳其语）

所以发布数据没有以正确的方式插入到数据库中，

这是我的节点 js 文件：

var data="ğüşıöç ĞÜŞİÖÇ"
var postdata="isim="+encodeURIComponent(data)+"";

var options2 = 
{
    host: "localhost",
    port: 80,
    path: "/bbb.php",
    method: 'POST',
    headers:{"Host":"localhost","Content-Length": postdata.length,'Content-Type': 'application/x-www-form-urlencoded'}
};

var post_req = http.get(options2, function (res) 
{
  var responseBody='';
  res.on('data', function (d) { responseBody += d; });
  res.on('end', function (d) 
  {
    sys.print(responseBody);
  });
}).on('error', function (e) {sys.print(e.message);});

post_req.write(postdata);
post_req.end();

这是 php 文件：

<?
header('Content-type: text/html; charset=ISO-8859-9');

$dbbaglanti=mysql_connect("localhost", "root", "");
mysql_select_db("db");
mysql_query("SET NAMES 'latin5'");


$isim = $_POST["isim"];
mysql_query("insert into deneme (isim) values ('".$isim."')");
?>

数据正在像这样插入到数据库中：ÄüÅıöç ÄÃÅÄ°ÃÃ

但我知道我是否在 php 中这样做：

$isim = iconv("utf-8","iso-8859-9",$_POST["isim"]);

数据插入没有问题 : ğüşıöç ĞÜŞİÖÇ

那么我怎样才能以正确的方式做到这一点？我用谷歌搜索了很多次，我无法弄清楚我该怎么做。我知道 nodejs 有一些 iconv 扩展，但它们适用于 linux 而不是 windows。 javascript或nodejs（windows）中有没有像iconv这样的方法？或 Windows 的任何扩展？或任何其他建议？

请不要说我把php的charset改成utf-8，我不能编辑php，我以localhost为例。

encodeURIComponent 总是编码为 utf-8（然后将生成的 utf-8 字节转换为百分比编码），所以我猜你必须使用一个库，或者自己滚动。我使用了我的一个库中的一些代码来制作这个：

var encodeURIComponentLatin5 = (function() {
