Lingo missing phonetic alphabet characters

I installed Lingo in Ubuntu 12.10 and the characters from the phonetic alphabet dont appear correctly. Am I missing some font that comes in Elementary and is not installed in Ubuntu?

This is the output I have once I open Lingo:

elementary - (??l????-m??n??t??-r??, -tr??)
1. adjective Of, relating to, or constituting the basic, essential, or fundamental part: an elementary need for love and nurturing.

Expected output:

ˌelɪˈmentri

(if your web browser can show it, anyway something similar to the output on this page http://oald8.oxfordlearnersdictionaries.com/dictionary/elementary )
