A 7 + rotated I (-) should give a Z, who agrees

I need help in modding because: How in the factori do i make recipes with REFLECTED LETTERS? What I mean is the notation for any letter that is reflected. What I do to make some letters not change their type is I just cycle around the same letter. But in this case, letters like L have special shapes by reflecting them horizontaly, verticaly or both....

I need help i want a mod that allows custom machines like you can rotate i by for example -17 degrees each time you use the machine OR a feature that star garden games adds. to: all the modders and star garden games

The recipe for letter K : I + Y "turned to the right", this one is not working at all for me...

i have completed all the main and secret levels and i'm a bit lost, can anyone help me with this?
