一 什么是Emoji  

emoji就是表情符号；词义来自日语（えもじ，e-moji，moji在日语中的含义是字符）
表情符号现已普遍应用于手机短信和网络聊天软件。
emoji表情符号，在外国的手机短信里面已经是很流行使用的一种表情。

在国内的微信和微信中也被采用。

    # browser sniffing tells us that a docomo phone
    # submitted this text

    $clean_text = emoji_docomo_to_unified($_POST[message]);


    ...


    # now we want to show it in a desktop browser

    $html = emoji_unified_to_html($clean_text);
?>
