it said that doesn't work, and ashley said to "Use the 'set character width' action with a space."
and on size, I was referring to the fact that adding details is much easier if you start with details to add to.
If a round corner has 3 pixels that form the arc, that is the best quality your are going to get. It you have 500 pixels in the arc, there is no mistaking it is an arc, and how much quality you end up with is your choice.
Or if the inside of the P is one pixel, no matter what filter you apply, it will never appear square on one side and round on the other. The highlights you apply will assume the wrong shape. While the pixel hole may be too small to notice, the highlight is not.
