I have adapted the guillemets in the free Google Libre Baskerville font for visual dialogue, and I can type and print fine from all native Mac applications such as Textedit, but the font doesn't appear or paste into a Word document. The instructions suggest that adding fonts to Microsoft Word for Mac is just a matter of adding them to your system with the Fontbook. This is not the case.
A metric view of the extended font is below. The saved .WOFF loads fine into my machine, and I can use it fine.
What must be done to allow Microsoft access to a new font on a Mac?
Here is the repertoire of the font showing my properly encoded glyphs in Fontbook.
