I am running Syncovery 9.47g on QNAP (x86).
Every single time a job is run, all files/folders with accented characters (á ã â ç é ê ü, etc.) are re-uploaded to pCloud.
Syncovery also reuploads all files within a folder with an accented character in its name, whether they have accented characters or not.
Caching the destination listing seems to solve the issue, but it shouldn't be necessary.
