Hi, Ingo!
I checked what you said. Changing the font doesn't help, The same problem with the characters in Firefox 2.0.0.11, Opera 9.25, IE7. Firefox Page Info says the encoding is utf-8.
The strings in db are not saved correctly. When I open a Content field in SiteTree_lang table via phpmyadmin I see only "Ãʉ۪àїàµáÂàÆá‹àµ! àўàѕà»áÊàÑâ€Ã Ñ• áѓ àÅà°áÃÆ’! Ãʉ۪á‹ áÃÆ’".
Phpmyadmin is set to utf-8. It says that the rows collation is utf8_general_ci.
But when I open a ss database to view the tables the collation is indicated as cp1251_general_ci.
Russian characters problem appears regardless of whether it is a translation or default language.
The site runs on a Russian server, where utf-8 wordpress (one language - Russian) works fine with the same parameters.
Just started to translate the content. It looks like I can't use SS for Russian content sites at all!
