Before version 3.4, EbookUI.FontName is effective to epub files, which allows us customize typeface.
However, 3.4 removed EbookUI from settings, and font name customization is only available at FixedPageUI.EbookFontName, which has nothing to do with EPUB.
It’s a breaking change making some customization unavailable in the current pre-release versions.
Can we expect EPUB FontName customization coming back when 3.4.x officially released? If not, is there some other way to adjust font name for reading epub files?
