JS无法解析具有Unicode字符的JSON [英] JS cannot parse JSON with unicode character

问题描述

我具有以下JSON字符串{"name":""C\u008cUR Carmen"}，但未解析\u008c.而是显示空字符.

I have the following JSON string {"name":""C\u008cUR Carmen"} but \u008c is not parsed. It shows empty character instead.

json = '{"name":"C\u008cUR Carmen"}';
json = JSON && JSON.parse(json) || $.parseJSON(json);

显示:CUR Carmen

期望:CŒUR Carmen

请帮助.

*注* :JSON数据由PHP服务器返回，因此不会出现任何语法错误，因为我使用了json_encode并从AJAX获得了响应.它可以与其他字符(例如à, é)一起使用，但只有此奇怪的字符不能正确显示

* Note * : The JSON data is returned by the PHP server so there shouldn't be any syntax error because I used json_encode and get the response from AJAX. It works with other characters such as à, é but only this wierd character doesn't display properly

编辑:已解决！这不是JS问题，而是MySQL返回的字符集问题.您可以在返回SQL数据之前使用mysql_set_charset('utf8').按预期显示\u0152

EDIT : Solved! It's not a JS problem it's a charset problem returned by MySQL. You can use mysql_set_charset('utf8') before returning SQL data. Show \u0152 as expected

推荐答案

无需转义 RFC 4627

2.5.字符串

字符串的表示类似于C语言中使用的约定 编程语言家族.字符串以开头和结尾 引号.所有Unicode字符都可以放在 用引号引起来，但必须转义的字符除外: 引号，反固相线和控制字符(U + 0000 通过U + 001F).

The representation of strings is similar to conventions used in the C family of programming languages. A string begins and ends with quotation marks. All Unicode characters may be placed within the quotation marks except for the characters that must be escaped: quotation mark, reverse solidus, and the control characters (U+0000 through U+001F).

您可以直接使用unicode字符串:

You can use your unicode string directly:

json = '{"name":"CŒUR Carmen"}';
json = JSON && JSON.parse(json) || $.parseJSON(json);

我认为您的服务器端实现中存在一个代码转换错误，您在使用json_encode之前将输出更改为ASCII. JSON要求所有数据均以Unicode编码.

I think there's a transcoding bug in your server side implementation where you change the output to ASCII before using json_encode. It is a requirement of JSON that all data is encoded in Unicode.

修改

在此小提琴中，有一个示例如何在javascript中还原转义的unicode.
