Is it possible to use Opentype's features like ligatures in Libreoffice? if yes, how?
Because as far as I know, in Ubuntu and Linux in general, these features are available only for graphite(aka smart) fonts like Linux Libertine G
(a free graphite font available here). Opentype fonts have the same features but not accessible in Libreoffice. I'd explain more if requested.
Please notice the differences in the snapshot. Ligatures are automatically being applied in graphite fonts. Word Arthur shows smallcaps feature.
