我正在尝试将网址插入包含scandic字母的数据库，例如：
ÄÖäöÅå
我正在使用：
当我尝试插入时，收到此错误消息：
字符串值不正确：'\ xC4HK \ xD6。
此查询确认已正确设置字符集和排序规则：
if (mysql_query("SET NAMES utf8mb4 COLLATE utf8mb4_unicode_ci")) {
echo "Character set OK !";
}
我的MySQL查询适用于除包含scandic字母的URL之外的所有内容：
if (mysql_query("INSERT INTO `table` (`address`) VALUES ('$URL')")){
$insertCount++;
echo "<br> insertcount = ".$insertCount."<br>";
} else {
echo "MySQLerror = ".mysql_error()."<br>"; // Show MySQLerror
这是来自MariaDB的MySQL信息，显示所有内容都设置为utf8mb4：

试试这个
验证存储数据的表是否具有utf8字符集：
SELECT
`tables`.`TABLE_NAME`,
`collations`.`character_set_name`
FROM
`information_schema`.`TABLES` AS `tables`,
`information_schema`.`COLLATION_CHARACTER_SET_APPLICABILITY` AS `collations`
WHERE
`tables`.`table_schema` = DATABASE()
AND `collations`.`collation_name` = `tables`.`table_collation`
;
检查您的数据库设置：
show variables like '%colla%';
show variables like '%charac%';
将utf-8更改为utf8_general_ci
ALTER TABLE tablename CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;

C4和D6是latin1 hex。
请SHOW CREATE TABLE查看相关列的CHARACTER SET内容。我怀疑它不正确latin1。
而且，是的，您必须从mysql_*界面切换。
