Previous topic was here, There should be an option to change the kanji font but it got closed because of no replies in a pretty long period.
However, I agree with this topic and the Jitai script, suggested in the only reply, only covers kanji fonts during review. I’d just like to set a site-wide font. Right now, the favored font seems to be “Hiragino Kaku Gothic Pro”, but, why not give us an option to set a font we like? No harm done if we make it a font that doesn’t exist. And no userscript needed either.
Please think about it.
