Our service has detected that Ukrainian is used on the page, and it does not match the claimed Russian language. Our system also found out that Developers.org.ua main page’s claimed encoding is utf-8.

For example, adding the following code snippet into HTML <head> tag will help to represent this web page correctly in social networks:
