微信文件传输助手网页版中文编码问题

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

…è“èè’è”±¨…‘°#TODS2023§ ” #TodsTheItalianPortrait ‘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 = "…è“èè’è”±¨…‘°#TODS2023§ ”\n#TodsTheItalianPortrait\n\n‘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"&轮精! `R!9`R&}#TODS20239 士系 #TodsTheItalianPortrait ::aWalter Chiapponi

下面这段：
“‰‰”±¤è…è§è°‰.

用windows-1252编码，然后utf-8解码后是：
. 当?微信版本?支?展示该内容，请?级至最新版本。.

通过网络搜索，发现正确的文字是:
当前微信版本不支持展示该内容，请升级至最新版本。.

部分文字无法解码

仔细分析“当”和“前”发现：

当 => [0xe5, 0xbd, 0x93] => “
前 => [0xe5, 0x89, 0x8d] => ‰ (这里8d没有对应的编码，导致编码出现问题).

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

查看原始网络数据包，发现字符串包含了部分不可见字符，比如: \x8D \x81.

所以如果要获得正确的编码，`iconv.encode('', 'windows-1252')` 之后要替换掉对应位置的值为81、8D、8F、90 或 9D。

现(utf8)=e78eb0=°(latin1)

@ntedshen 似乎不对?
> iconv.encode('现', 'utf-8')
<Buffer e7 8e b0>

> iconv.encode('°', 'latin1')
<Buffer e7 3f b0>

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')
