I was wondering if the Kobo rendering engine supports font ligatures. And by support I mean that if the source text contains just the normal individual characters but a font contains proper ligature definitions, the ligature is displayed. Like this (

where the text is simply "venezuela fixture exitoso". The bottom row shows the ligatures for "ez", "fix", "ex", "os" (it also shows terminal letters, but that's a different feature).
