Hello @brokvolchansky,

Thanks for the report and the reproducer, that was very helpful!

I created a ticket to fix this problem. I will check with the team if we can tackle it for the next release. In the meantime, the only workaround I can offer is to rely only on ASCII characters in file names or paths.

Thanks again for reporting

Your ticket says that the bug was already fixed in version 10.9, but the bug is still reproducible in version 10.18.0.80657

Hi @Yura,

Welcome to the community!

Can you provide a full log, please?

 
Thx,

Hello @Yura,

The original bug was fixed but unfortunately there are similar occurrences in other places. I created this ticket to fix them. We will try to prioritize the fix for the next release.

Thanks for reporting!
