Greek language font, signs etc.

Hello, there is some bugs that appears on all minecraft versions and its about the greek language.
So: The font of the greek language on menus is unicode and that is sucks and on multiplayer chat some of the greek letters is unicode and some like a bold (impossible to read easy) characters... Also the greek language cant be added on signs etc.
Why that injustice to the Greece who also pays money for minecraft? Please look at it. Thanks!
