Month Names in different languages

[altryne]

OK guys I searched for this and what I found helped a bit but there's still a problem
I use 2 language packs in my shop
russian and hebrew

in both of them I got the months names in english language...
I mean the string "New products for" was in my language(either hebew or russian) and the month name itself (eg. August) was in english
So I went to heberw.php after reading here and changed setlocale to 'hebrew'
and it worked
ok so I was happy and went to russian.php to do the same thing
I changed it to 'ru_RU' and to "russian'
and all I get is question marks
I counted them... and it seems that the month name is displayed in correct but just doesn't allow russian characters...
The rest of the site displays russian language just fine...
Plz help
