DB collation and chartset setting in Mysql (in Laravel)

问题

I am using external DB(charset:latin1_swedish_ci, collation=latin1, MyISAM) with internal DB(utf8mb4_unicode_ci, utf8mb4, InnoDB).

• customer_name : collation = utf8mb4_unicode_ci
• customer_email : collation = utf8mb4_unicode_ci

So everytime I get the below exception warning when getting data from external DB.

How should I modify DB setting in my situation? Thanks.

If that was supposed to be ø, then you need do one of two things:

• Switch the encoding of text in the client from latin1 to UTF-8.

• Tell MySQL that the client is conversing in latin1.

Other charset debugging: Trouble with UTF-8 characters; what I see is not what I stored
