Hungarian Umlauts

How to get true Hungarian umlauts in Type 1 Bembo in MS Word 2010

I'm using a Type1 Bembo in MS Word 2010 and I need to set the lower case "o" with Hungarian umlauts. Can this be accomplished? I have the Expert Set and the SmallCaps set, but neither of those contains the character I need.

Any help would be appreciated.

Many thanks,
