Best solution for Mysql error in rails 4 app 'Incorrect string value'?

+2 votes
89 views

I have a rails application, in which I am using delayed_job_active_record gem for running background jobs. While using the method .delay with an object, I am getting the following mysql error:

"INCORRECT STRING VALUE: \'XE2X9CX93"X0A ...\' FOR COLUMN \'HANDLER\' AT ROW 1"

I already searched for the above error and found that its because of the difference in encoding in mysql and rails. The solution suggested by many programmers is to alter the encoding in mysql database to utf8. But I also read that MySQL's utf8 charset only partially implements proper UTF-8 encoding. It can only store UTF-8-encoded symbols that consist of one to three bytes; encoded symbols that take up four bytes aren't supported. Which might cause trouble in some other cases. Also, when I tried to insert the value directly in mysql, it worked like a charm. Suggesting that the issue might lie elsewhere. So, can anyone please suggest the right method to rectify this problem?

Any help would be greatly appreciated.
