Gallery non-Roman text

I'm back with another question to which I suspect I already know the answer.
In the story I'm currently telling, the main character speaks Russian and I had initially written the text using (Unicode) Cyrillic. When I pasted the text into the gallery text entry box, all of the non-Roman text were dropped.
Is that expected?
