I believe this issue has come up before with a similar patch but someone checked their ncurses and they didn't see the same issue. I just checked and here mvwaddchnstr() does not expect a null-terminated string either, but it skips the \0 characters. So probably we should replace them with spaces or something else, I wouldn't like to replace a single library call with 80 calls, it's better to go through the string and replace them, maybe in console_write_ch or somewhere else. Cheers
