As has been discussed on this list, the "em" value is eaqual to the height of the font, not the width of the "M" glyph. CSS1 does not have "en" -- use "0.5em" instead. "ex" is the only one that can pose problems. Some font formats will tell you the x-height independent of the "x" glyph (which often is slightly higher). If you don't get any such value and have no "x" glyph, I'd suggest making "ex" a fixed fraction of "em" (e.g. 1ex=0.4em).
