Since 30 about 1.3.1 one can start java with the option -Dfile.encoding=UTF-8, but 31 unfortunately this works only with later update - versions (for example, 32 1.3.1_07). Therefore we use this scheme. The property string has this form: 33 name=value 34 35 Every character is cast to an integer which value is printed, followed by a 36 space.
