コーディングが不十分なフィルタースクリプト（もちろん、本当にあなたが作成したものです！）のおかげで、データベース内の危険な文字にいくつか問題がありました。
PHPMyAdminからSQLファイルとしてデータをエクスポートしてデータを修正し、間違った文字を入念にCTRL+H検索して正しい文字に置き換えました。次に、PHPMyAdminを使用してSQLファイル（3つの別々のファイル）を再インポートしました。
これはほとんどのデータで問題なく機能しましたが、いくつかの投稿では完全に途切れているようです。

しかし、何らかの理由で、種のプロファイルでわかるように（そして、データベースでもまったく同じです）、そのテキストのほとんどが欠落しています。
これを引き起こしている可能性のあるアイデアはありますか？インポートによってエラーが発生することはありません。
