我正在使用一个过程来转储数据库内容并编写一个文件 sql ...

一切正常，但在我的文件中，所有具有特定字符（如 è、àù éç 等）的数据都在文件中丢失了......我现在有点困惑。...我必须在哪里设置正确的字符集？

我的数据库有一个默认字符集 UTF8 和排序规则 UTF8_general_ci

在我的服务器端脚本中从数据库中正确处理数据（CRUD 正常工作并且数据正确显示）。当我在变量中获取数据并将完整的 SQL 过程写到文件中时，重音字母会损坏......

这是我的转储程序，它返回我的数据库的完整转储

尝试在之后添加此代码SET NAMES utf8; 或使用mysqldump实用程序。

SET character_set_results = 'utf8', character_set_client = 'utf8', character_set_connection = 'utf8', character_set_database = 'utf8', character_set_server = 'utf8';
