Russian names are broken in archives from owncloud, how to fix it?

Question

Character encoding

Dear community, help solve the problem with encoding in owncloud when downloading folders with archives. There is a NAS (Nas4free), fs - ZFS and a server with Debian 7 on which the ball is mounted from this NAS (SMB or NFS), the Russian names of folders / files from the balls inside penguinux are displayed correctly, in owncloud itself there are also no problems with encoding, and when downloading a whole folder, owncloud automatically packs it into an archive, all Russian names become krakozyabry. Although, if you create a folder from owncloud itself on the same ball and place files and folders with Russian names inside, then when you download the folder, all the same archive, all the names are reflected correctly in Russian, tell me where to dig, otherwise I already broke my whole head.
