Cyrillic font

I noticed that on the home page the heart cloud contains several words written with the Cyrillic font. Can you explain how to do this?

I didn't completely get your question. By this moment all Tagul fonts support Cyrillic characters, so you may feed your cloud with an URL that contains cyrillic words (e.g. http://news.google.ru) and build it. They should be shown in your cloud without problems.
If you experience problems let me know what exactly does not work.

P.S. Thank you for the first ever post on the forums!
