問題描述我們上報(bào)頁(yè)面title 偶爾有這樣的亂碼 類似這樣(這是四條亂碼):2019?1′è????????è??????,"??????????§°???é?3??°???????1???o???,2019?1′è????????è????????è?2?ˉ1??￡????-|??????è??èˉ???￥?????????-é??è???????????, ???èˉo???è·??o???°???MP80????¤??°?é?± è§?? ??????° ?????? é??è′-???-è￥????問題出現(xiàn)的環(huán)境背景及自己嘗試過哪些方法發(fā)現(xiàn)有的是ua是百度爬蟲造成 所以我們過濾掉了ua帶spider字符串的情況,但是還是發(fā)現(xiàn)有這樣的問題相關(guān)代碼// 請(qǐng)把代碼文本粘貼到下方（請(qǐng)勿用圖片代替代碼）title: encodeURIComponent(document.title)
