Obliques are when the Roman (plain, whatever you care to call it) face is algorithmycally *slanted* whereas Italics are faces drawn deliberately at an angle and usually the characters are different from the Roman face. that sounds confusing to me, but it's rather tough to explain it without visual aides. 2:^) oh, what the heck, here goes nothing... 00000 000 0 0 0 0 00000 0 0 0 0 0 0 0 0 0 00 00000 0 0 00 Roman lowercase a Italic lowercase a ok, now here's a slanted "Oblique" lowercase a: 00000 0 00000 0 0 0 0 000000 0 i think that should help explain... notice how i took the Roman face and put it at a slant? that's basically what they do... cheers.--d -- "Ein zwei drei vier...
