Wow, that's awful.

At first, this code wouldn't run because for some reasons Thunderbird 
treated the K in the lines
     char[] K = new char[256];
and the first K in this line
    int K = 0, Κ = 0;
both as 0x4B, thus making the code erroneous. Or maybe it was one of the 
newsservers that made the substitution.

I never knew that Java allowed Unicode letters in the source code, so I 
even learned something new today.

Thanks for sharing,
Stuart
