When I open Latin Modern in FontForge, I see two types of ascent and descent values: the ones in the "General" tab are 806 and 194, and the ones in the OS/2 tab, in particular Win Ascent and Win Descent, are 3560 and 3060. Such a discrepancy does not seem to exist in the few well-behaved fonts that I checked. > > Could it be that most applications use the first set of values, but Emacs relies on the second? Maybe. I know nothing about these internals of the fonts, sorry. I hope someone more knowledgeable could chime in and tell us what, if anything, to do with this discrepancy.
