DecodeURIComponent 不支持 %uXXXX 编码组件
DecodeURIComponent is not supporting for %uXXXX encoded component
DecodeURIComponent 不支持少数编码组件
我在 json 和 restapi 中发送公告格式的 JD。所以我正在编码 jd 并发送。这在没有任何 issues.But 的情况下正常工作，当我尝试解码编码的 JD 时，我收到错误消息，因为 URI 格式错误
var jd = "Where are bullets most often used?
- Technical writing
- Reference works
- Notes
- Presentations";
var json ={
"job":encodeURIComponent(escape(jd));
}
解码：
var jd = decodeURIComponent(jd);
这是我从响应中得到的编码 jd。

你必须先unescape它
var jd = decodeURIComponent(unescape(json.job));
避免使用 escape()。
来自文档：
escape()
The escape() function computes a new string in which certain characters have been replaced by a hexadecimal escape sequence.
Description
The escape function is a property of the global object. Special characters are encoded with the exception of: @*_+-./
The hexadecimal form for characters, whose code unit value is 0xFF or less, is a two-digit escape sequence: %xx. For characters with a greater code unit, the four-digit format %uxxxx is used.
Deprecated. Not for use in new websites.
来自维基百科：
There exists a non-standard encoding for Unicode characters: %uxxxx, where xxxx is a UTF-16 code unit represented as four hexadecimal digits. This behavior is not specified by any RFC and has been rejected by the W3C. The third edition of ECMA-262 still includes an escape function that uses this syntax, along with encodeURI and encodeURIComponent functions, which apply UTF-8 encoding to a string, then percent-escape the resulting bytes.
