HttpQueryInfo function 文章中有这么一段话：
Note The HttpQueryInfoA function represents headers as ISO-8859-1 characters not ANSI characters. The HttpQueryInfoW function represents headers as ISO-8859-1 characters converted to UTF-16LE characters. As a result, it is never safe to use the HttpQueryInfoW function when the headers can contain non-ASCII characters. Instead, an application can use the MultiByteToWideChar and WideCharToMultiByte functions with a Codepage parameter set to 28591 to map between ANSI characters and UTF-16LE characters.
估计 "WinHttp.WinHttpRequest.5.1" 对象用的就是 HttpQueryInfoW 函数吧。
如果使用 HttpQueryInfoA 则可以正确转换编码。AHK 代码示例：
