Ubuntu 12.04 MySQL cannot be started after UTF-8 is changed

Default-character-set = utf8

Error:

Start mysql. The restart (8) utility is also available.
Start: Job failed to start

So OK:

On MySQL 5.5 I have in my. cnf

[Mysqld]
Init_connect = 'set collation_connection = utf8_unicode_ci'
Init_connect = 'set NAMES utf8'
Character-set-server = utf8
Collation-server = utf8_unicode_ci
Skip-character-set-client-handshake

Result is

Mysql> show variables like "% character %"; show variables like "% collation % ";
