Avant Garde Gothic - Extended character sets?

[_Ben_Marshall_]

I am working on a project for a client in Poland. We have been given regular and bold weights of Avant Garde Gothic with extended character sets that cover the Polish language. Now however, we want to use the medium weight as well, but have no idea where one goes to find a special extended character set. I have tried numerous type websites with no luck. Any help would be great :)

There's an Avant Garde CE Gothic Demi, available from Linotype. It
appears to be Adobe's with the Central European character set added.
(I don't understand that at all!)

URW may also have a Medium version. I have one whose font name may be
AvantGarGotItcTEEMed. I don't know if it's still available.
