Missing characters in Indesign

[labestianegra]

How to add character to Indesign which doesnt show up in glyphs of a certain font, but I can see exists when I look in Fontlab? I am missing characters č, ć, ž etc. in indesign for cccomicrazy, but they all exist in fontlab 8

Does it show in the Glyphs panel within InDesign?

Here's how the Glyphs panel for that font looks when installed on my machine:

It doesn't seem to have any of the glyphs you're looking for.  If you follow @Mike Witherell 's advice and look for those glyphs in your Glyphs panel and don't find them, can you then post a screenshot of what it looks like in Fontlab?
