russian characters not accepted in php / phpmyadmin?

I have a website in 3 languages: english, dutch and russian.

There's a little CMS where the user can update the text on the website.

everything works good, except for the russian text.. If I enter any russian text 开发者_运维知识库in the form in the CMS, I get "????" in the phpmyadmin database and on the website.

I am completely new to charsets, it's the first time I am building a website in a language that is not supported like in this case..

Could someone please tell me what's the problem here? and what I have to do to make this work in russian language?

The problem is that you haven't told your database to support multibyte characters. Set it to use UTF-8.
