characters in length issues should not be encountered, irrespective of
cloud storage provider.
An experimental advanced option `filename_encoding` is now provided to
address this problem to a certain degree.
For cloud storage systems with case sensitive file names (e.g. Google Drive),
`base64` can be used to reduce file name length.
For cloud storage systems using UTF-16 to store file names internally
(e.g. OneDrive), `base32768` can be used to drastically reduce
file name length.
An alternative, future rclone file name encryption mode may tolerate
backend provider path length limits.
