I want to use the ruby program to read the mysql database written by a php program and find that all Chinese characters are garbled, similar to the following: 刘佳.

If mysql query browser is used for connection, garbled characters are displayed in mysql,
I can see that the database encoding is UTF-8, And the php reading is displayed on the page, but the Chinese is displayed normally.

Why is ruby garbled? Is there any way to solve this problem?

require 'active_record'class Student < ActiveRecord::BaseendActiveRecord::Base.establish_connection(  adapter:  'mysql2',  host:     'xxxx',  username: 'xxxx',  password: 'xxxx',  database: 'xxx_db',  encoding: 'utf8')puts Student.first.name

Output result刘佳
PHP displays correct resultsLiu Jia
