我们公司的网站是个zencart电商网站
网站所有文件格式都是utf-8 无bom编码格式
网站录入数据时都先运行 sql:"set names utf8"
数据库中所有数据表都是 utf8 格式
但某些外国用户在我们网站上注册或者编辑信息，录入数据库时会出现乱码，这种情况出现率5%左右。为什么会出现乱码？怎么解决？
回复讨论(解决方案)
他浏览的时候的浏览器的网页编码可能不是utf8的，或者是翻译后浏览。可以用javascript得到客户端的编码
utf8_general 也有及少量的未收录的字符，例如俄罗斯的少数民族。但是这个原因的可能性极小，远远到不了5%。
出现乱码就是编码问题。
你的数据都是post方式提交到数据库的把？
会不会跟我用ajax post提交有关？

注册时就是ajax提交生成账号
两个解决方案：
1.ajax提交的时候，用+encodeURIComponent方法编码。
2.php端可以检查提交的是否是utf8编码。
