There is not much in world what supports an very special language, like hungarian. But I always hope that I will met such sets like Libertine, that you could use not only free desktop publishing, else any purpose what you prefer.
After I have red that news the new Libertine set is released with new typographic modifications, specially targeted with some solved hungarian letter spacing problems, together with other small beauty repairs – what makes more usable at TeX environment too – made me very happy. This set hold 4 other types, and small capital type too, together with some letter equalisation, what means not just real levelling between letters (like in TeX: the Modern Computer set), else this is the first OpenType set what is usable perfectly with OpenOffice too. Such doesn’t existed – until yet. The best is – the licence is GNU GPL and SIL OFL.
