How to use Cyrillic in Report Module

Hi!
I am trying to use report module which Data has Header with Cyrillic symbols.
screenshot.su/show.php?img=1ae1a … 201851.jpg
screenshot.su/show.php?img=8b30d … 2c1856.jpg
and about of this I have this results
screenshot.su/show.php?img=24b24 … baa363.jpg

What is the solution of this problem?

I’ll take a look at this today…

Out of curiosity, what number format symbols do you have set up for that column?

I was able to replicate this. Looks like the reporting engine is not happy with keys that contain letters outside of 7-bit ASCII. I’ve made a ticket to fix this.
