Synch fails synchronizing files with problematic filenames.

[minguo33]

An entire synchronization crashes when trying to 1 synch file with a problematic name. Deleting the file on the server side allowed the merge to finish.

Filename was generated by the App using dynamic file names. (Field worker presumably entered data into the wrong field with question marks included)
