Any renderer that does this is wrong. 1em is a unit a measurement that means "the current font size". So, 1em could mean to render an entity to 4pts or 3000pts...or any size in between.
Now, if you meant to say "most renderers set the default font size to 12 points", then that's as may be, but it's not the same thing as saying "12pt = 1em" or "1em = 12pt".
