Shawna, I found your author!
Take a look at:
https://dspace.ucalgary.ca/browse-author?top=Austad%2C+Michele+L
(you may need to 'next page' if any authors have been added after I sent
this)
All hail the multi-byte character ordering!!
Anyway, after testing your specific scenario, the ISO-Latin character
filter won't actually fix this particular issue (Ž isn't an ISO-Latin
character).
It could be fixed with the java.text.Normalizer - except that it only
exists in JDK 1.6 :-(. However, IBM offer basically the same thing, free
and open source, under the X public license.
If you download the icu4j-3_6.jar from here:
http://icu.sourceforge.net/download/3.6.html#ICU4J
(place in the lib directory) and apply the attached patch, this will
normalize diacritics as they are entered into your system.
The patch also includes a simple class that removes diacritics from
sort_author in the existing rows in the ItemsByAuthor table.
After patching, installing jar, running 'ant update', etc., from your
dspace installation 'bin' directory run:
dsrun org.dspace.browse.NormalizeSortAuthors
to 'fix' your existing entries.
