How to use Cyrillic in Report Module

I am trying to use report module which Data has Header with Cyrillic symbols. … 201851.jpg … 2c1856.jpg
and about of this I have this results … 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.
