我使用学说查询生成器来筛选记录，这是我认为这是导致问题的一部分：主义LIKE带俄语字符

$query = $query->where('i.offernumber LIKE :search') 
    ->orWhere('o.client LIKE :search') 
    ->orWhere('o.sticker LIKE :search') 
    ->orWhere('o.gu LIKE :search') 
    ->orWhere('o.project LIKE :search') 
    ->orWhere('o.quantity LIKE :search') 
    ->orWhere('o.date LIKE :search') 
    ->leftJoin('o.previous', 'p') 
    ->leftJoin('p.input', 'pi') 
    ->orWhere('pi.offernumber LIKE :search') 
    ->setParameter('search', "%".$search."%");

的问题是，我得到以下错误，当我输入俄文字母人物：

An exception occurred while executing 'SELECT c0_.id AS id0, c0_.client AS client1, c0_.quantity AS quantity2, c0_.next AS next3, c0_.status AS status4, c0_.date AS date5, c0_.sticker AS sticker6, c0_.gu AS gu7, c0_.project AS project8, c0_.completed AS completed9, c0_.rversion AS rversion10, c0_.input_id AS input_id11, c0_.previous AS previous12, c0_.user_id AS user_id13 FROM crm_order c0_ LEFT JOIN crm_input c1_ ON c0_.input_id = c1_.id LEFT JOIN crm_order c2_ ON c0_.previous = c2_.id LEFT JOIN crm_input c3_ ON c2_.input_id = c3_.id WHERE c1_.offernumber LIKE ?

SQLSTATE[HY000]: General error: 1271 Illegal mix of collations for operation 'like'

什么可能会造成这个错误，并且是有办法解决这个问题？

围绕推动代码，并试图各种组合之后，我精确定位错误的原因，它的这2条如下因素线：

->orWhere('o.quantity LIKE :search') 
->orWhere('o.date LIKE :search')

Apratently那些2个变量不是字符串（数字和日期的MySQL类型），并且上面的查询尝试为“LIKE％string％”查找不是字符串类型的列它会导致错误。与此相同的问题post

对于这个问题，有什么可能的解决方案，因为我仍然需要搜索字符串，数字和日期？

你有没有在config.yml设置字符集
