should accept special characters for file names
Synchronizing with OneDrive for Apple Computers is otherwise nearly impossible, as Apple accept Special characters e.g. / for file names!!!

Renaming the files is impractical when backing up large collections, e.g. iPhoto/Photos experts. An special character - even a trailing space or period - can cause entire folders, albums, etc. not to be backed up.

DropBox never complains that the name of a file contains a special character — it just makes it work. I'm trying to move from DropBox to OneDrive and I'm told I have to rename 165 files?!
