I’ve updated one site from 095 to 096RC3.
Cyrillic strings, which I enter in the manager get smashed in the DB — as

?????.
On the web-site they appear in a wrong way as well.
Other sites with RC3 work.
Content, entered before update is seen perfectly in DB and on the site.
Everything is set to utf-general-ci.
MySQL Server version: 4.1.21-standard
