在Node.js中将字符串从ISO-2022-JP转换为UTF-8

Question

我有一个ISO-2020-JP编码文本的Buffer，我需要将其转换为UTF-8。我在NPM上找到了一些库，比如:

• encoding-japanese
• iconv-lite

但是我不知道，也找不到，到底哪个编码对应的是ISO-2020-JP。请建议。

Answer 1

你可以使用encoding.js.

const Encoding = require('encoding-japanese');

const buffer = [27, 36, 66, 36, 51, 36, 115, 36, 75, 36, 65, 36, 79, 27, 40, 74]; // こんにちは in ISO-2022-JP
// if you want to convert an ISO-2022-JP byte array to a UTF-8 byte array:
const utf8Array = Encoding.convert(buffer, {
to: 'UTF8',
from: 'JIS'
});
console.log(utf8Array);
// if you want to convert ISO-2022-JP byte array to JavaScript string:
const unicodeArray = Encoding.convert(buffer, {
to: 'UNICODE',
from: 'JIS'
});
console.log(Encoding.codeToString(unicodeArray));
