Diacritical marks are truncated via Active Record

Solved!

I changed my db config from char_set utf8 to utf8mb4.

Here's a solid summary of the issue and solution:

Code:

   
   'char_set' => 'utf8mb4',
   'dbcollat' => 'utf8mb4_general_ci',

The article implies that this solution would work only with PHP versions > 5.5.3, but fortunately it's working fine in v5.3.29.
