Looked. But...not all characters shown :(

Hello everyone,

I would like to ask one question about fonts.
Situation: I live in Lithuania, we use some special characters. I also love gothic fonts...and could find none that has *all* the characters.
Yes, I tried search there, typing all special characters...and getting no font (out of ~300) that has them all.
Question: do you know any font, paid or free, that:
a) is close to authentic mediaeval and
b) has all Lithuanian characters, i.e. would corrently display all of them?
