[Owncloud] special characters in filenames

[Frank Karlitschek]

Hi everyone,

we have an interesting question where I would love to get some more opinions.

The question is how ownCloud should handle special characters in filenames. ownCloud itself should work always with UTF8 and do proper encoding so that ownCloud can work with all possible characters.
The problems are the underlying filesystems.

So the ownCloud server can run on Windows/Linux/Mac servers with lot´s of different filesystems and we have clients for Windows/Linux/Mac/iOS/Android with more different filesystems. All this filesystems have limitation for allowed characters and handling of uppercase/lowercase filenames.

So what can/should ownCloud do if someone want´s to sync a file with a special character that´s supported on one platform but not on another?
Should be change the filename? Or don´t sync at all?

What do you think?
