使用UTF 8编码查询字符串的htaccess RewriteRule问题

Question

我们有一个基于Prestashop的电子商务网站，并启用了友好的网址。

带有这样的查询字符串的url工作正常。 http://www.mywebsite.com/en/validation?response_text=test

不验证带有UTF 8编码字符串的查询字符串并抛出404页面错误。 http://www.mywebsite.com/en/validation?response_text=PD94bWwgdmVyc2lvbj0iMS4mVxdWVzdCB4%0AbWxuczp4PSJod
