我从web服务收到Ajax响应，我不确定字符是什么。我需要将它们转换为ASCII/UTF-8等效文件，但我不知道从哪里开始。
其中一些字符的示例是：
'x3d1
'x26pf
'x3dp
'x26s
'x3dpsy
'x26
原始JSON响应来自Google Suggest：

这看起来像URL编码的字符。通常情况下，您不需要转换任何内容。例如，如果您从AJAX调用中获得以下字符串：
var x = ''x3d1'x26pf'x3dp'x26s'x3dpsy'x26';
如果你试图打印它：
alert(x);
它应该显示正确的值：
=1&pf=p&s=psy&
我认为你应该试试这个函数utf8_decode
