Question

最近我注意到在我的数据库中一些 unicode字符（大多数是日语）变成了难以理解的垃圾。例如：

「オリジナル」桜庭わかな - 远游荡〜7つめのアレクトラ

变成了

：一种€Œã,ªãƒªã,¸ãƒŠãƒ«ã€æ¡œåºã,ã<ãª - 远wanderingï½ž7ã¤ã,ã®ã，¢ãƒ¬ã,¯ãƒãƒ©

数据来自YouTube API（使用PHP），然后放入我的数据库。我想谷歌可能会在短时间内破坏某些东西然后修复它。但是现在由于封闭频道和/或已删除的视频，我无法使用Youtube API获取大量数据。

我已经尝试过：

将列转换为latin1 / blob / binary =＆gt; UTF8
将几行转储到文件中，然后在Notepad ++中打开sql文件并更改字符编码（希望字符集设置错误）
要求进行最早的备份恢复 - 它已经存在了

有没有办法将其恢复到以前的状态？

我被告知我服务器上的mysql使用的是xtradb而不是InnoDB。以下是有关我的数据库和表格的信息
