Encoding problem (Hebrew UTF8) in WordPress

I have a blog (of a friend) I am failing to fix:

http://www.nivcalderon.com/

The language of the website is Hebrew, but the encod开发者_StackOverflow社区ing scrambles the output, and I can't find how to fix it.

I tried changing the DB colliation to be utf8_general_ci.

I added this:

define('DB_COLLATE', 'utf8_general_ci');

To the wp-config (and also this: define('DB_CHARSET', 'utf8'); But removed it later, since it didn't seem to fix the problem)

Any ideas of what else to do ?

Thanks

The issue is causing because of a bad import, which make the database to contain double-encoded utf-8 strings. It can be fixed by exporting the tables as latin1 and than importing it as UTF-8. This is not a WordPress fault.
