/** This class prints out the system properties.

    We cannot print the strings directly because of encoding issues. Since
    about 1.3.1 one can start java with the option -Dfile.encoding=UTF-8, but
    unfortunately this works only with later update - versions (for example,
    1.3.1_07). Therefore we use this scheme. The property string has this form:
    name=value

    Every character is cast to an integer which value is printed, followed by a
    space. If all characters of the string are printed, then a new line is printed.
