Hello Ken, others,

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.
I have been thinking through this. It seems quite appealing.
But I'm concerned there may be some edge cases. I have been able to come
up with two so far:
- Applying this to a string starting with upper-case SZ (U+1E9E).
This may change SZ → ß → Ss.
- Using the 'capitalize' method to (try to) get the titlecase
property of a MTAVRULI character. (There's no other way
currently in Ruby to get the titlecase property.)
There may be others. If you have some ideas, I'd appreciate to know
about them.
This lets me wonder why the UTC didn't simply declare the titlecase
property of MTAVRULI to be mkhedruli. Was this considered or not? The
way things are currently set up, there seems to be no benefit of
MTAVRULI being its own titlecase, because in actual use, that requires
additional processing.
