(resent from address that is subscribed to the list) Hi Uli,
The code to create the URL was using: NSURL *url = [[self courseDirectory] URLByAppendingPathComponent:name]; where [self courseDirectory] is a URL of a directory (with an English name created by the app) in the Documents folder. The variable "name" is a NSString that is from the user (with just basic sanitizing to replace "/" with "-"). Note: this is iOS. So I wasn't using UTF8String or fileSystemRepresentation. Someone claimed I should be using fileSystemRepresentation and someone else said it shouldn't matter. If anyone has the definitive answer as to what I should change that to, I'm happy to use it (although it may be too late now).
