中文被 json_encode 編碼成 unicode 之後如何轉換回中文

使用 php 自帶的 json_encode 函式對資料進行編碼時，中文都會變成 unicode，前面我介紹瞭如何使得中文不被 json_encode 不編碼成 unicode。

如果已經被 json_encode 編碼成 unicode 之後，怎麼轉換回中文呢？可以使用下面該函式將 unicode 進行轉換：

function wpjam_unicode_decode(KaTeX parse error: Expected '}', got 'EOF' at end of input: …)/i', function(matches){
return mb_convert_encoding(pack(“H*”, $matches[1]), ‘UTF-8’, ‘UCS-2BE’);
}, $str);
}
該功能已經整合到 WPJAM Basic 外掛中，並已免費提供下載！
