In our days there is no one universal standard for presenting Cyrillic (aka Russian) text on the web. So I created this page to test what are the possible encodings that we can deal with. In addition to the different encodings, I give english translation, a bitmap image of the text and a transliterated version. Let's look at what we have here:

Encoding   Alternative Names   Meta Tag  UCS-2 Unicode, all double-byte UCS-2 UTF-8 Unicode, Little-Endian (Windows) UTF-8 KOI KOI8-R, KOI8, UNIX koi8-r Win Windows, win-1251, CP1251, Win-Cyrillic  windows-1251 DOS CP866, IBM-866, DOS-866 cp866 ISO ISO-8859-5, SUN iso-8859-5 Mac Mac-Cyrillic x-mac-cyrillic KOI-U KOI8-U, KOI8-UR koi8-u ShiftJIS Shift-JIS Shift_JIS Unicode Big-Endian  UTF-8 FFFE unicodefffe

So go ahead and click on buttons and see what you browser will display, for the comparison use the Image one, also you may want to play with charset meta tags and find out how well you browser can auto detect an encoding.
