bad encoding in redmine2.2.2 projects

Hello, i have upgraded bitnami_redmine from 2.1.2 to 2.2.2 version. Upgrading proccess was succesfull, but in my projects wrong encoding.

Database upgrading process:

1. dump current database: mysqldump --default-character-set=utf8 --complete-insert --user=user -pxxxx redmine > file_name

2. create database in new bitnami_redmine stack: CREATE DATABASE db CHARACTER SET utf8 COLLATE utf8_general_ci;

3. restore dump in new database: mysql -u user -p db < file_name

4. edit database.yml to new db

On last upgrades it works fine, but now thereis a bad encoding in my projects...

Maybe it's because of a new mysql2 adapter?
