Bill Jouris,
I am sorry for the belated response. I have been listening to the talks on "Latin Diacritics" during the past few CPWG Calls. My good friend Satish Babu is also with this Working Group.
Attached please find:
J. Victor Gaultney, "Problems of Diacritic Design for Latin Script Text Faces" Dissertation submitted in partial fulfilment of the requirements for the Master of Arts in Typeface Design, University of Reading, 2002
This dissertation is 32 pages.
The core technical challenge stems from the fact that many characters with diacritics can be represented in the following two ways in Unicode.
#1. Precomposed Characters: A single code point is assigned to the letter and its diacritic together.
#2. Combining Characters: The base letter has one code point (e.g.,
e is U+0065), followed by a separate code point for the diacritic mark.
These two forms are visually identical but have different underlying code points. This can cause problems in data transfer, searching, sorting, and comparison unless the data is properly
normalized to a single form.
I prefer #2 for the sheer genericity and it can easily become a part of a larger patch of Application. I suppose we can assure "Upward Compatibility" and progress.

Hi Christopher,
Just to be clear, I tried (and apparently failed) to make clear that, while I am a member of the Latin Diacritics Working Group, I was speaking strictly in a personal capacity, and not on behalf the WG.
That said, I appreciate the support. And that of Sergo Salinas of LACRALO, who also spoke on the subject.
