Strongly agreed.

The problem with Unicode is its main aim of allowing characters of 
multiple writing systems in the same text. When multiple writing systems 
are in play, conflicts and ambiguities will appear.

I solved my problem by writing an Alphabet hierarchy in the past. I 
don't like that code but it still works:

 
https://bitbucket.org/acehreli/ddili/src/4c0552fe8352dfe905c9734a57d84d36ce4ed476/src/alphabet.d#lines-50

It handles capitalization, ordering, etc. I use it when preparing the 
Index section of the Turkish edition of "Programming in D":

One of the ambiguities is what came up on this thread: Should a word 
that starts with I (capital i) be listed under I (because it's Turkish) 
or under İ (because it's English)? So far, I am lucky because the only 
word that starts with I happens to be the English "IDE", so it goes 
under i (which appears as İ in the Turkish edition) and would make sense 
to a Turkish reader because a Turkish reader might (really?) accept it 
as the capital of ide.

It's confusing but it seems to work. :) It doesn't matter. Life is 
imperfect and things will somehow work in the end.
