Unicode Symbols in Shared Font Libraries

I am working on a project using an unusual unicode glyph set. The language is Salish, a Native American language of the Northwestern United States. I can get the glyphs to show up when I embed the unicode font directly into the text field with the unique characters added to the embedded font list, but they don't show up when I use the same font that is included through a shared font library. Is there a way to make sure the font library I create by making font symbols contains and displays the glyphs I need?

Thanks.
