<div dir="ltr"><div><div><div>Hi again,<br><br></div>I tried my luck with fontforge even though I have no idea how to use that program. Nevertheless I managed to measure the distance between the baseline and the lower spline of U+2192, arrowright, and of unicode U+2212, minus.<br>
</div>I have no idea in which units fontforge displays the distance but the lower line of "arrowright" lies at height 268 and the lower line of "minus" lies at height 298. This might be more informative for some of you than the pdfs I created.<br>
