RemoveWinForbiddenChars removes characters which are forbidden on a Windows server from the name of an uploaded file.  Characters will be replaced by Windows-legal characters of the same length.

When uploading from a certain client machines (such as Mac), filenames may contain characters which are not allowed on a Windows server, such as "\", ">", and "*".  By default, JFile will replace these characters with "_", or with "_-_" for the "%2f" character ("/" or "|") to keep the same name length.

If you wish to prevent filenames from being modified, set RemoveWinForbiddenChars to "0".
