Resolving This Error
Special characters can often cause problems with file handling systems, either when you cross from one type of operating system to another (e.g., Mac to PC), or when you use various protocols (e.g., WebDav, HTML). It is generally best to avoid their use if possible. Even though the file may save fine in one place, it's file name may cause an issue when transferred elsewhere.
While some characters like "-" are almost always acceptable, it's a good practice to consider if your special characters are causing your issues whenever you run into a problem opening or moving files.
