Yes lots of things in that ad (https://www.youtube.com/watch?v=UJ2z1be2EXQ https://www.youtube.com/watch?v=UJ2z1be2EXQ) are impossible with the UK teletext they're trying to emulate, generated by a Mullard SAA5050 (there were others). It also takes a whole character (for the control code) to switch foreground or background colours. The fonts and graphics pixel sizes are all over the place, the only 'pixel' art available used a 2x3 grid within each character.. If they wanted a more faithful font there are plenty around, I've even done a couple myself: https://github.com/glxxyz/bedstead https://github.com/glxxyz/bedstead and https://galax.xyz/TELETEXT/ https://galax.xyz/TELETEXT/
