Have you tried to add lyrics with non standard alphabets?

Here's my second problem, I'm working on a piece based on a Mayakovsky poem, and I'm writing a baryton part that will be sung in russian. So I add the lyrics in Cyrillic doing copy paste from the poem.
The problem is that once I've added the lyric I can't modify it anymore! It sticks on the page and no double click is allowed.
Is there a solution for this ?
Thank you
