nostt is a command line reader for NOS Teletekst, the Dutch public teletext system (like Ceefax in the UK). It supports color and has an interactive mode. Note that teletext supports 6-cell (2x3) block drawing characters. The NOS viewer and API use a custom font with these characters in the "private use" 0xF000 Unicode range. Because such characters are not usually available on terminals, they are replaced by % characaters.
