Mixing keywords together

Latin and Cyrillic letters

[abrodski]

Hello!

If I want my site to be found by someone who doesn't type in English, can I add words in Russian to the list of english keywords...
So it would look like this:
keyword, ключевое слово, форум, forum

In Joomla I can make a list of keywords and so far I only use words in English.

Of course, I was talking about SEO keyword list (just to make it clear)...
