Binkie, you certainly haven't given anything away to me!
As far as
Doric is concerned, it does seem to be written always with a capital D. It's another one of those cases (as we've talked about in previous topics, a non-amos) where a word that is derived from a person or place name retains an initial capital, even though the word itself is not a proper name. In this case, the word originally meant pertaining to the Doris region of ancient Greece, so it still has a capital letter, even when it is used for a style of architecture or, more specifically, column design. So that's why it's not allowed in Chi.
On the other hand,
uber is a more border-line proposition. Anonsi suggested it a while ago, and
my response then was that it seemed to be used in English as a prefix rather than a word in its own right. But I'm ready to be persuaded if anyone can present evidence to the contrary.
