Hello,
I will try to clarify: I am well aware of the existence of many software
projects using IDS, or other hierarchical structures, to describe
ideographs. I assume they will all have to deal with cases where a component
of an ideograph isn't itself a character. My question was specifically about
the possibility of encoding such components, rather than leaving it to be
resolved separately in each project (e.g. by using PUA characters,
indicating variants or abbreviations of existing characters etc). I hope it
is clearer now. If examples (websites of such projects) are desired, please
let me know.
I've recently been supplementing an existing list of decompositions for CJK
Unified Ideographs, and have so far found several dozens of such repeating
components which aren't encoded characters. This doesn't include the
extension blocks, for which I don't have decomposition data (but have found
quite a few components in). I would therefore estimate the number of
components at several dozens or perhaps a few hundreds, depending on the
policy of suggesting new ones.
Regards,
Uriah Eisenstein
