   6     We cannot print the strings directly because of encoding issues. Since
   7     about 1.3.1 one can start java with the option -Dfile.encoding=UTF-8, but
   8     unfortunately this works only with later update - versions (for example,
   9     1.3.1_07). Therefore we use this scheme. The property string has this form:
  10     name=value
  11
  12     Every character is cast to an integer which value is printed, followed by a
  13     space. If all characters of the string are printed, then a new line is printed.
