I am adding polytonic Greek to a font family and have a question concerning alternate glyphs. After looking at numerous examples there doesn't appear to be a standard for the iota diacritic glyphs especially for small caps versions. Here is what I have designed so far — please ignore spacing, etc. as this is still a work in progress. The base glyph is uni1F8A with/without hanging diacritics, then an alternate with a regular iota instead of the iota diacritic, then a small cap uni1F8A, then a cap/small cap of it, last a small cap with a reduced iota diacritic. My question is do I need all these and have I forgotten any variations such as cap/small cap hanging diacritic? I don't want to go overboard, but as long as I am doing it I feel everything necessary should be included.
We are using ITC New Baskerville and InDesign for a semi-annual publication, unaware that this font set lacked several Greek symbols (e.g., kappa, chi, omega). A new ITC New Baskerville Pro version may add a few Greek symbols, but none of those mentioned. We can make do with substituting another font, if we have to, but a bigger problem arises in translating from an original document in WORD Times Roman to ITC New Baskerville in InDesign. This process leaves no marker specific to the original Greek symbol.
(1) is there a complete ITC New Baskerville font set available that has the key Greek symbols needed for statistics?
