My question:
Why evaluation signs (+-, +/-, +=, better is, worse is, etc etc) of the PGN file don't appear? (I had to type them each _by hand as text_ in order for you to see them here...)
I tried copying the original PGN from the Chessbase in different formats (old pgn, new pgn, old text, new text, html) but the evaluation signs simply didn't show here. They always lost somewhere.
Please tell me if you know the answer!!!

Just examine below the original PGN I inserted and try to download it from the Java appication above. (You will notice the difference--all the normal evaluation signs have lost somewhere in the process... You will see only those typed in by hand--as text.)
