Cyrillic causes an error
Blazer queries cannot handle cyrillic strings in clauses.
Steps to reproduce: try to select anything from any table WHERE text_field LIKE "%любойтекст%" or WHERE text_field = 'текст' and the error will appear.

Hey @klarazetkin, I'm not able to reproduce. Can you paste the stack trace?
Unfortunately, I'm not sure how to get the stack trace. If no tips, I'll ask our devs in the morning. :)
It should be in the application logs (you'll probably need a dev to access it).
Hey, please, don't close the issue. We're doing hard to check it, lol.
Cleaning up stale issues - can reopen if there's more info to reproduce
