file_standardize

 FILE_STANDARDIZE: Remove all the characters that might be source of problems when in filenames.

 USAGE:  filename = file_standardize( filename, isFullPath, repchar )
         filename = file_standardize( filename, isFullPath )
         filename = file_standardize( filename )

 INPUT:
      - filename   : name of file or full path to standardize
      - isFullPath : if 0, simple filename => remove '/' and '\'     (DEFAULT)
                     if 1, full path to filename => keep '/' and '\'
      - repchar    : replacement character (default '_');
 
 OUTPUT: 
      - filename   : standardized filename
