For example, if we type "A" on the keyboard, it will also be displayed as "A" on the screen.
And some of fonts are designed to do this another shape which like more large or bold.
I think, This is the only thing what we can do by changing font.
But some special fonts are designed to do this different shape.
For example, when I type "A" but it will be displayed "B" on display. Also "C" to "D", "F" to "A", etc..
I want to know how to make this TTF file.
And is it possible to restore original font? or Can is find its transform rule?
I don't know it is not allowed in stackoverflow, but if you want i give you example fonts.
