“ This is important for accessibility reasons, as not all fonts are as readable for everyone, and different reading environments may have different needs (e.g. on the web, on paper or on an e-reader) .
In particular, Wikisource does not seek to force all texts to be be in the same or similar fonts to how they were published. ”

“ A very limited amount of font manipulation is permitted where such a thing doesn't impact readability and provides added value to the work or helps distinguish content where such distinction was made in the original work. It is extremely unusual for entire blocks of text to be set in a specific font. ”

“ UniversalLanguageSelector Wikisource uses the Extension:UniversalLanguageSelector extension to enable users to set their font preferences for the entire site, including the menus and other user interfaces. ”
