如何在mysql或php中将'u00e9'转换为utf8 char？

Question

我正在对一些混乱的数据进行一些数据清理,这些数据正被导入到mysql中.

数据包含'伪'unicode字符,它实际上作为'u00e9'等嵌入到字符串中.

所以一个字段可能是..'Jalostotitlu00e1n'我需要撕掉那个笨拙的'u00e1n'并用相应的utf字符替换它

我可以在mysql中使用substring和CHR执行此操作,但是我通过PHP预处理数据,所以我也可以在那里执行.

我已经知道如何配置mysql和php来处理utf数据.问题实际上只是在我导入的源数据中.

谢谢

/*函数php将utf8 html转换为ansi*/

public static function Utf8_ansi($valor='') {

    $utf8_ansi2 = array(
    "\u00c0" =>"À",
    "\u00c1" =>"Á",
    "\u00c2" =>"Â",
    "\u00c3" =>"Ã",

有一种方法.uXXXX用他们的HTML表示替换all 并执行html_entity_decode()

即 echo html_entity_decode("Jalostotitlán");

表单中的每个UTF字符u1234都可以用HTML格式打印ሴ.但是进行替换非常困难,因为如果没有其他字符标识UTF序列的开头,可能会有很多误报.一个简单的正则表达式可能是

preg_replace('/u([\da-fA-F]{4})/', '&#x\1;', $str)
