Opentype features in Libreoffice

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.

Solution 1:

First way is about font features of Linux Libertine G and Linux Biolinum G include extended font names for LibreOffice:

Linux Libertine G:smcp=1 for small caps

Linux Libertine G:pnum=1&onum=1 for proportional & old style numbers

Read more here, and also you can use Typography toolbar for LibreOffice.

Second view for a problem is a letter "G" in the font name what have the meaning that this font is ready for use by SIL Font Graphite Technology.

Solution 2:

LibreOffice has had support for Opentype features since version 5.3 released in February 2017. This guide explains how to use them.

In brief, you need to turn on Opentype features by editing the four letter codes into font names. Click the font name and move the cursor to the end. Type a colon, then the four-letter code for the Opentype feature you want to enable, for example

Libertinus Serif:onum

To turn off a feature that is on by default, you can add =0, eg

Libertinus Serif:liga=0

To turn on multiple features:

Libertinus Serif:onum&pnum
