In bittorrent sync version 1.4.75 and 1.4.83 any file names containing Korean characters will not sync. The log files on both machines indicate that the files are skipped due to an "invalid UTF8 file name". This problem did not exist with version 1.3.109. The problem seems to be unique to Korean characters. I've tried both Chinese and Japanese and files with these characters synchronize properly. System Information: Gentoo Linux Kernel Version 3.14.14 File System: ext4 cat sync.log |grep -i version version: 1.4.83 The relevant section of the sync.log file is shown below.

From the web UI on two different machines choose a folder to synchronize. 2. Go https://translate.google.com/?hl=en#en/ko/Thank%20You to generate some Korean characters. 3. Open a terminal and cd to the shared folder on Linux machine Alice. 4. Type "touch 감사합니다.txt" 5. Type "touch hello.txt" 6. Wait 5 minutes and observe on Linux machine Bob that the 'hello.txt' file has arrived but that the file with Korean characters has not been received. 7. Open the sync.log on Alice and look for the line "Skiping file '감사합니다.txt' with invalid UTF8 file name". 8. Bonus observation: 'Skiping' is spelled wrong in the log file. Expected result: Files with Korean characters are not skipped.
