Encountered a strange problem when working with EzPortal after periehal 2.0RC5.
His (portal) is also required to upgrade to version 0.5.1, 0.3.6 previously used - had no such problems, but he did not go to the new version of SMF, had put the last EzPortal. And the fact the problem is that after saving the Russian text in EzBlocks further errors are shown to the encoding of all kinds. Roughly, it is clear that the case here with the encoding, but how can I fix it? I take a long time EzPortal and have no desire to move to another portal. Please help if you can do in this situation.
And this is how it all looks like:

Make sure all the ezportal tables in the db are set to utf8

All ezportal tables in the db are encoded "cp1251_general_ci".
Necessary to convert to UTF? How can I do?

P.S. However, in EzPortal 0.3.6 version similar problems were, but only with EzPages.
With EzBlock everything was fine. Please help!

Might be the issue
$blockdata = htmlentities($_REQUEST['blockdata'],ENT_QUOTES);

Not sure if it works for UTF8

Might be the issue
$blockdata = htmlentities($_REQUEST['blockdata'],ENT_QUOTES);

Not sure if it works for UTF8

$blockdata = htmlentities($_REQUEST['blockdata'],ENT_QUOTES);changed to
$blockdata = htmlentities($_REQUEST['blockdata'],ENT_QUOTES,UTF8);no significant changes.
The problem with encoding is not allowed.
...And the choice "cp1251" map is also wrong, but of another kind.

I'm not a programmer, and not quite understand what may be other solutions in this situation.
What other possible actions needed to solve the problem?
