About line spacing

mauro sacchetto

I did an experiment to adapt a Simoncini font; I'm currently working on Debian Linux with FontForge. But I'm pretty confused.

I've run into a problem with line spacing:

In the texts I type with LibreOffice, if I set the metrics as shown in the image, the lines are extremely narrow, to the point that the capital accents intersect with the descent glyphs. You can see this in the attached image. However, everything works with other fonts, even though they have completely different settings: Adobe Text Pro sets Typo Line Gap: 200 and Line Spacing: 200, while EB Garamond sets Typo Line Gap: 0 and Line Spacing: 0:

With LibreOffice, the lines are properly spaced only if I set the Typo Line Gap value to very high values ​​(at least 300). If I use the same font with LaTeX with the above settings (and not big Typo Line Gap, but set to 0), however, there's no problem.

Is this problem due to some intrinsic feature of the font, or could it be caused by other incorrect or missing data? Let me know if any other information might be helpful.

Thanks
