Ken, Markus,
Many thanks for your ideas, which I noted at
https://bugs.ruby-lang.org/issues/14839.

My questions here are:
- Has this been considered when Georgian Mtavruli was discussed in the
UTC?
Not explicitly, that I recall. The whole issue of titlecasing came up
very late in the preparation of case mapping tables for Mtavruli and
Mkhedruli for 11.0.
But it seems to me that the problem you are citing can be avoided if you
simply rethink what your "capitalize" means. It really should be
conceived of as first lowercasing the *entire* string, and then
titlecasing the *eligible* letters -- i.e., usually the first letter.
(Note that this allows for the concept that titlecasing might then be
localized on a per-writing-system basis -- the issue would devolve to
determining what the rules are for "eligible" letters.) But the simple
default would just be to titlecase the initial letter of each "word"
segment of a string.
Note that conceived this way, for the Georgian mappings, where the
titlecase mapping for Mkhedruli is simply the letter itself, this
approach ends up with:
capitalize(mkhedrulistring) --> mkhedrulistring
capitalize(MTAVRULISTRING) ==> titlecase(lowercase(MTAVRULISTRING)) -->
mkhedrulistring
Thus avoiding any mixed case.
