I just realized that Obsidian uses the “Regular” variant (just slanted) of the font for italic text although there is a separate “Italic” variant for this which looks much nicer:
Looking at the font settings under Appearance > Text Font I can only choose between these two options:
On macOS, it looks like the PostScript name is iAWriterQuattroV-Regular so that’s what you’d type here and/or use in a CSS snippet. It should be similar on Windows, but can’t verify that at the moment.
Okay, so this may be a Windows issue with variable fonts (I was using the mac until now in my previous screenshots) or the actual font files themselves. I know Quattro has the wrong font weights, and that doesn’t seem to have been fixed. I noticed that issue when installing Quattro on iOS a while ago.
Windows 10 won’t let me install both iAWriterQuattroV.ttf and iAWriterQuattroV-Italic.ttf for whatever reason. iAWriterQuattroV.ttf will install, but when installing iAWriterQuattroV-Italic.ttf, the regular version is removed (and neither show up in the Fonts list).
I’d try installing the static versions to see if you have any better luck with those.
Thanks so much for taking the time to check this out!
I just installed the Static version (which runs as iA Writer Quattro S) and it works right out of the box (but only after rebooting Windows, Obsidian didn’t recognize the font even after restarting the app). Looks so much better now.
Also thanks for the hint about font weights, that was another thing that drove me crazy…
