What this site says seems pretty clear to me:

H&FJ's Greek character set covers Modern (monotonic) Greek.

Too bad!

Figgins Sans’ Greek is quite similar to Whitney’s, and has polytonic and other Greek options.
See pages 55-57 of the PDF:

BTW is Whitney the only H&FJ face featuring non-Latin scripts?

Nick, I don't get to pick the typeface on this one. For good or ill, the client has specified Skolar for the text, with Whitney display. I don't have the MS in hand yet. If there is polytonic Greek in the display, we'll have to figure something out. Oh well, that's what comps are for. Get the accents/breath marks from a different font, & place by hand... very slowly...

Hrant:

Maybe. It's hard to figure out from all their advertising, but so far, it seems so. I take

In preparation for moving its library into OpenType, H&FJ established the Language Research Program in 2005, in order to develop updated specifications for its Latin-based character sets. The initial product of this research is H&FJ’s Latin-X™ character set, which expands the reach of a typeface to an additional 200,000,000 readers worldwide. This character set reflects not only a more accurate awareness of the political landscape of language, but the most up-to-date understanding of cultural norms.

to be an attempt to put a positive spin on the fact they aren't offering OpenType fonts yet. Just look at the pricing for "Basic" & how much more adding the small caps is (and as a separate set of fonts, which means even more more handwork for use). The "multiscprit" fonts cost more than twice the "basic," a pricing I find predatory. Of course, I'm a curmudgeon...

I've always taken H&FJ to be in the advertising world, one which has rare overlap with books. Their pricing models seem to fit that, too. But again, I'm a curmudgeon...

Maybe the client needs to be made aware that Whitney is simply a poor choice for polytonic Greek (even though it does have a lot of other good qualities). It's not like there's a shortage of humanist sans fonts...

Charles -- H&FJ may not have been offering OpenType at the time that was written, but they certainly are now. I can't comment on their Greek support.

Here is what they state on Whitney Multiscript Edition:

Whitney Multiscript Edition — Best Value
The complete Whitney collection: a single set of OpenType fonts integrating the Pro editions of all three character ranges (Latin-X™, Greek, and Cyrillic-X™). Includes Romans, Italics, plus Roman Small Caps and Italic Small Caps, each in six weights (Light, Book, Medium, Semibold, Bold, and Black), with tabular figures, fractions and extended symbols for each font style — plus the sixteen-style Whitney Index family.

+35 minutes...
I was wondering what "Roman smallcaps" and "Italic smallcaps" mean. Looking at their Character set, it seems there is neither Greek smallcaps, nor cyrillic smallcaps.

No biggie, Cyrillic has smallcaps built-in. ;-)

You mean the Whitney *Manuscript* bundle for $600? As opposed from the *Advanced* for $300 and the *Pro* for $500? (For one computer.) These are current offerings. It looks like, except perhaps for manuscript, the more expensive bundles -- which do add glyphs -- also add to the number of fonts in the bundle, which I take to mean the extra glyphs are in separate fonts.
