请问有人知道这里的原始中文编码是什么? 如何解码?

json 返回的字符串

流畅轮廓、精致细节和自由律动，糅合呈现#TODS2023秋冬 男士系列。
#TodsTheItalianPortrait

创意总监：Walter Chiapponi

实际内容

流畅轮廓、精致细节和自由律动，糅合呈现#TODS2023 秋冬 男士系列。
#TodsTheItalianPortrait

创意总监：Walter Chiapponi

询问了几个 AI, 基本都建议这样解码:

const iconv = require('iconv-lite');
const garbledText = "流畅轮廓、精致细节和自由律动，糅合呈现#TODS2023秋冬 男士系列。\n#TodsTheItalianPortrait\n\n创意总监：Walter Chiapponi";
const buf = Buffer.from(garbledText, 'binary');
// const decodedText = iconv.decode(buf, 'windows-1252');
// const decodedText = iconv.decode(buf, 'latin1');
// const decodedText = iconv.decode(buf, 'gbk');
const decodedText = iconv.decode(buf, 'utf-8');
console.log(decodedText);

但是实际输出是这样的, 只有小部分内容被解码:

流�"&轮�㬁精�!�� �`�R�!����9�`��R�&�����}�#TODS2023�9� � ��士系���
#TodsTheItalianPortrait

@ntedshen 似乎不对?

3f 是问号

其实不用管这个，你现在只需要知道编码是错的，接口无论如何也不可能给你一个拉丁字符集让你自己处理中文。。。
看看 contenttype 是不是没 utf8

我知道原因了，windows-1252 的 81 、8D 、8F 、90 和 9D 都未有使用( https://zh.wikipedia.org/wiki/Windows-1252 )

所以下面的中文编码为 windows-1252 ，然后重新解码 utf-8 部分中文会出错。

iconv.decode(iconv.encode(iconv.decode(iconv.encode('流畅轮廓、精致细节和自由律动，糅合呈现#TODS2023 秋冬 男士系列。#TodsTheItalianPortrait 创意总监：Walter Chiapponi', 'utf-8'), 'windows-1252'), 'windows-1252'), 'utf-8')
