While all other applications can properly display e.g. Tifinagh letters, Maperitive using Mono does not.
Example: "Rabat ⴰⵕⴱⴰⵟ الرباط" is shown with Rabat and الرباط properly, but the Berber version is shown as meaningless sqares. Same for East Asian fonts.
Platform is Lubuntu 16.04 LTS, latest patch level.
PS: when I make the Tifinagh TTF the only font (move out all others, run fc-cache -fv), then the Latin and the Arab letters are displayed in Tifinagh, but the Berber letters remain squares :-((
Anybody out there ??
