Thanks for testing.

That'd be too much, IMO. current-column is called in many places, and
it would be unexpected for it to return different values depending on
the font and the frame. The correspondence between these two
functions is not 100% now anyway (e.g., current-column is sensitive to
auto-composition-mode, whereas string-width isn't).
Lisp programs that need 100% accuracy in these matters should call
window-text-pixel-size.
