For example, in TrueType fonts, there is a field called unitsPerEm, and the glyphs are specified in terms of coordinates in that space. The designer does not have to make the em square be as wide as the letter M. The glyphs can protrude outside the em square. On the other hand, TeX appears to define "em" in terms of the letter M or m. So TeX and CSS appear to be different in this area. Erik
