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 certain client systems (such as Mac), file names 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 file names from being modified, set RemoveWinForbiddenChars to "0".
