Debug logs: link
Description of issue: Logs are full of errors like the following, which seems to happen anytime a series contains any episode with an accented character in the filename.
Couldn't rescan series [427464][The Walking Dead: Daryl Dixon]: File doesn't exist: /Volumes/Video/TV-US/The Walking Dead - Daryl Dixon/The Walking Dead - Daryl Dixon - S01E01 - L'Âme Perdue.mkv
If it matters, the Video volume is an NFS mount of a Synology shared folder. The debug log linked above includes the debug data around one such instance, but the rest are identical aside from the series and episode title. Any accented character seems to throw the error (accents, umlauts, etc.). Not expecting any “help” per se but at least reporting what appears to be a bug.
