When the strike passes the edge of the circle, it's no longer a zero, it's a Danish or Norwegian "Ö" (Ø). It's been a part of their alphabet for centuries.
The whole purpose of the "strike through zero" is to stop it from being mixed up with Omega. By badly thought out design and a need to be different for no reason, you just returned to square one, because the font is now unreadable for anyone that knows or works with the letter Ø.
