25 /** This class prints out the system properties.
26 
27     We cannot print the strings directly because of encoding issues. Since
28     about 1.3.1 one can start java with the option -Dfile.encoding=UTF-8, but
29     unfortunately this works only with later update - versions (for example,
30     1.3.1_07). Therefore we use this scheme. The property string has this form:
31     name=value
32 
33     Every character is cast to an integer which value is printed, followed by a
34     space. If all characters of the string are printed, then a new line is printed.
