Body:
I implemented option one and rebuilt displaytag. It works quite well, even
without passing the Locale to the Collator, as a default RuleBasedCollator has
a rule set which sorts most languages much more "naturally" than does
String.compareTo.
In order to have RowSorter.checkNullsAndCompare actually use the Collator
however, you must also modify the first 'if' clause to filter out Strings,
since they implement Comparable and would otherwise never reach the clause
which uses the Collator:
if (object1 instanceof Comparable && object2 instanceof Comparable
&& ! (object1 instanceof String && object2 instanceof String))

Feature: take extended ascii into account when sorting
strings
Solutions:
-Option 1
in RowSorter.checkNullsAndCompare
change the last else condition:
<code> // if object are not null and don't
implement comparable, compare using string values
returnValue =
object1.toString().compareTo(object2.toString());</code>
to:
<code>Collator.getInstance().compare(object1.toString(),
object2.toString());</code>
It's simple and it basicly solves the problem
-Option 2
When creating the TableModel in TableTag pass in the
locale and make it an attribute of RowSorter, then
<code>Collator.getInstance(locale).compare(object1.toString(),
object2.toString());</code>
It's a little more impacting but it sovles the problem
more generally
