Right, and that's by design.

I don't think there is a way to do that, if all you have is the frame
pointer. text-scale-mode does not modify the frame's default font, it
remaps the 'default' face to another face which specifies a larger or
a smaller font. So the way to find the width of the font after
scaling is to get hold of the font itself, or of the face to which
'default' was remapped. Then you can use FONT_WIDTH, I think (but I
didn't test this).
