I need this icon to design something (in typography).
Now, I just noticed it today... at some places this icon has +45 angle of the diameter and at some places it has -45, as show in the image:
Is only one of them is correct?
OR there is a specific rule like: To represent something is banned or not allowed, you can use a circle and a tilted line on it, irrespective of the angle?
Also, can we alter the width of the tilted diameter line? Or it should be same as the width of circle?
