a simple maquillage, unfortunately
I mean ancient greek font so that you can, typing ‘a’ get immediatly ‘α’. So far the free most interesting true type font (the only recognised by LibreOffice) is SPIonic.
Absolutely to avoid the “AncientGreek” extension: cumbersome, useless and very aggressive (after removing leaves you with modified shortcuts, including some basic like ctrl + z, ctrl + b and F3).Vey bad!
a new solution
I noticed that the above solution works only within LibreOffice: if you copy a greek word in another program, you get a no-greek text (with latin encoding). That’s why I call it now a maquillage.
A possible, better solution is go to a website that easyly encode your text in ancient greek, such as this.
