Check encoding for this page in your browser's settings.
Try opening the same page in other browsers.

Same problem at 1.5.2 version.

Marat, I was not able to reproduce the issue in 1.5.2.
Try SPIDER-L33T' suggestion.

Thnx, i will try. 

Maybe this info can help you:

When i stay at Gropus list page - all ok:

And page encode = utf-8

When i go to group info page when i see (all meny in cyrylic):

And page encode automaticaly go to Cyrylic (windows).

The same in admin plugin:

All check all files from ow_plugin\groups for file encode = utf-8.

Thnx a lot

Marat, when you have created this group and added title, description and etc. which encoding was used  in your browser? Seems like data ( text) was saved in database in incorrect encoding.

Try creating new group in another browser, make sure that it is using utf8.

I am still not able to reproduce the issue on my end.

this is problem not about data or browsers encoding. 

Why is that when the page is rendered with a group there is a change in the response header from the server to windows-1251.If you set in config file 

 define('OW_DEBUG_MODE', false); - TRUE 

then encoding ok. I don't find any in php code. 

But if i cut this^

  $componentPanel = new ADMIN_CMP_DragAndDropAdminPanel($place, $dbComponents);        $componentPanel->setPositionList($dbPositions);        $componentPanel->setSettingList($dbSettings);        $componentPanel->setSchemeList($schemeList);

from admin->panel then encoding for page admin Ok..... 

http://friendfish.ru/groups/1  - see response header (windows1251 - not ok)

http://friendfish.ru/groups/   - see response header (utf8)

Admin page (admin/plugins/groups) like groups/1/ response header 1251

CLOSE BUG.

My web-server have default charset windows1251. 

But groups plugin don't set in PHP headers...

My fix in .htacces setdefault charset

Thnx
