Convert iso-8859-1 to utf-8 javascript
提问by MrBinWin
I try to parse a "iso-8859-1" page and save to my DB with utf-8, this is my code:
我尝试解析“iso-8859-1”页面并使用 utf-8 保存到我的数据库，这是我的代码：
var buffer = iconv.encode(data, "iso-8859-1");
data = iconv.decode(buffer, 'utf8');
It doesn't work. All symbols like ? or ? convert to ???
它不起作用。所有的符号都像 ? 或者 ？转换成 ？？？
How can I save these symbols?
如何保存这些符号？

You need a third-party library for that task. You are using iconv-liteso you need to follow these steps:
你需要一个第三方库来完成这项任务。您正在使用iconv-lite，因此您需要执行以下步骤：
Open input file in binarymode, so JavaScript doesn't assume UTF-8 nor try to convert to its internal encoding:
var fs = require("fs"); var input = fs.readFileSync(inputFilePath, {encoding: "binary"});Convert from ISO-8859-1 to Buffer:
var iconv = require('iconv-lite'); var output = iconv.decode(input, "ISO-8859-1");Save Buffer to output file:
fs.writeFileSync(outputFilePath, output);
以二进制模式打开输入文件，因此 JavaScript 不会假设 UTF-8 也不会尝试转换为其内部编码：
var fs = require("fs"); var input = fs.readFileSync(inputFilePath, {encoding: "binary"});从 ISO-8859-1 转换为Buffer：
var iconv = require('iconv-lite'); var output = iconv.decode(input, "ISO-8859-1");将缓冲区保存到输出文件：
fs.writeFileSync(outputFilePath, output);
If unsure of encoding names, you can test whether a given encoding is supported with encodingExists():
如果不确定编码名称，您可以测试是否支持给定的编码encodingExists()：
> iconv.encodingExists("ISO-8859-1");
true

It's working for me:
它对我有用：
var tempBuffer = new Buffer(response.body, 'iso-8859-1');
var iconv = new Iconv('ISO-8859-1', 'UTF-8');
var tempBuffer = iconv.convert(tempBuffer);
used 'iconv' module https://github.com/bnoordhuis/node-iconv
