Customize theme, use new font file, no effect

[liutianyan]

Whether it is installed through a description file or a third-party app, and appears in the font list, it cannot be used in font-family.
Later, I switched to @font-face. But still no effect.

These two approaches are effective on macOS.

Are you using font-face with base64 or files? If you are using files, have you declared them in Info.plist?

Thanks for the reply, I used base64 encoding
I refer to the Hyperlegible.nnwtheme theme and don’t see any special settings in Info.plist?
