Trying to process a bunch of MP3 files with Unicode (Russian) names and metatags and get a bunch of exceptions in the log that look like these (do not mind Старые ПеÑни о Главном in the name of the file, it's a web display log bug, it must look normal in the actual log file):

Btw, I do not have any files (or folders) with the name Старые Песни о Главном - 1. The series folder is called Старые Песни о Главном (1996), under which there is Season 01 folder, under which there are episodes with standard naming convention, such as Старые песни о главном - s01e01 - 1 серия (1996).mkv. I also checked the .nfo files and I do not see this exact name.

The log message is showing the name of the item from metadata - not the file or folder name.

Oh, okay. I'd suspect that file name would be more useful in the log file for troubleshooting (metadata can be totally wrong, but file name would always point to the correct file), but regardless, do you need any additional info? Anything else I can help with to troubleshoot this issue?
