Macron for "oo" using Cronos Open Type
I've searched through all the glyph palettes and have not been able to find a glyph for the "oo" with a diacritical marker (macron) over it. All the single vowels have this glyph, but I've not found one for this particular combination. It's an Open Type font purchased from Adobe in the late 1990's. I know it's possible to make it manually but I would prefer to have it as a glyph if possible, for better consistency.
