On a lark, I decided to put some additional strain on the database and went looking for Russian LJers. When I joined back in the middle of last year, there were two users signed up from the Russian Federation, and I don't think either of them had posted in months.
Today, there are quite a few (almost 280).
Unfortunately, Cyrillic only shows up on my screen (Windows 98) if I look at someone's journal page. If I look at their posts via my friends page, or if I look at a comments page, the text is rendered as a series of mostly vowels with diacritical marks, which tells me that the original posts were not made in Unicode or UTF-8. (OTOH, when I look at the representation of the Russian I posted a bit earlier here via the Web client, I see, e.g., "Я" for the letter "Я").
Maybe when all of the excitement has died down with the latest round of mods, I'll take it up with support.
Cheers...
P.S. I went and edited the style of my friends page to include a META header that declares the page's contents to use the Windows-1251 charset. It's a workaround that will work - at least on my friends page - unless I need to see diacritically marked vowels (in which case they'll show up as Cyrillic letters).
