Our service has detected that Russian is used on the page, and it matches the claimed language. Our system also found out that Tera.su main page’s claimed encoding is iso-8859-1. Changing it to UTF-8 can be a good choice, as this format is commonly used for encoding all over the web and thus their visitors won’t have any troubles with symbol transcription or reading.
