This function removes all reserved characters: (less than), (greater than), (colon), (double quote), (forward slash), (backslash), (vertical bar or pipe), (question mark), (asterisk), and empty spaces, from the file name. This is important when writing a list of objects to an external file (e.g. KML) as it prevents from creating erroneous file names.
