Kepler? It isn’t as rationalised as most Didones, but is definitely in that classification.

Or Storm’s Walbaum?

I think Kepler is a great font, but not a Didone.
It’s Transitional (as lousy a term as that is.)

Recently, URW++ has been offering all of their fonts in OpenType PS format in various levels. “Level 1” OpenType fonts from URW++ contain Western & Central European characters, “Level 2” OpenType fonts from URW++ also contain Cyrillic and Greek.

Bodoni Antiqua and Corporate A fonts are offered with the WGL4 character set (West, CE, Cyrillic, Greek):

More URW++ Didone fonts with just Western and CE can be found at:

ParaType also offers a version of PT Bodoni that includes Western, CE and Cyrillic characters:

Note that ParaType’s Cyrillic version are design-wise usually much better than URW++’s.

[Kepler is] Transitional (as lousy a term as that is.)

Well you know what terminology I prefer: Didone = Romantic (e.g. Didot, Bodoni), Transitional = Neo-Classical (e.g. Baskerville, Bulmer).

Kepler is interesting because it really is transitional, occupying a space somewhere between neo-classical and romantic, but a bit too informal to comfortably occupy either.
