`Sanitize` tag should fix my problem with synchronization

[idle-code]

In two of my Seafile repositories exist paths that cannot be synchronized due to "The file path contains symbols that are not supported by the Windows system". The Sanitize tag should take care of it.

Seafile code responsible for checking if the path is valid on Windows can be found here: https://github.com/haiwen/seafile/blob/f3b2eb7372eabcf1d1c267d8ed4a72fa8be5e1e3/daemon/repo-mgr.c#L1432
