strange character at the end of 16x2 LCD

hello

i have a 16x2 LCD hooked up on my arduino mega according to the serial input example and basically everything works fine. exept that i have a strange character at the end of the word. it looks like sone japanese character. i used the original source code and i did not alter it at all.
btw, same happens when i try my duemillanova. both arduinos generate the same issue.
any idea?

the hello world example and all the others work without any problems. its just the serial input example.

thanks

i used the original source code and i did not alter it at all.

What original source code? Modified or not, the best way to get help is to post the code that is causing you problems.

Look for things like lcd.println() in the code. The LCD doesn't know what to do with a carriage return/line feed that the println() function sends. So, it shows something. Not always (ever?) what you want.
