  21 /** This class prints out the system properties.
  22
  23     We cannot print the strings directly because of encoding issues. Since
  24     about 1.3.1 one can start java with the option -Dfile.encoding=UTF-8, but
  25     unfortunately this works only with later update - versions (for example,
  26     1.3.1_07). Therefore we use this scheme. The property string has this form:
  27     name=value
  28
  29     Every character is cast to an integer which value is printed, followed by a
  30     space. If all characters of the string are printed, then a new line is printed.
