Body:
I agree that it would be very useful to be able to sort column contents using a
Collator, in order to get linguistic, rather than lexicographic ordering of
values. In any implementation which is based on the Collator.compare() method,
it would be useful be able set not only the current Locale, but also the
Collator's strength (whether to differentiate upper/lower case and
accented/non-accented characters) and decomposition (how the actual string is
decomposed into a sortable character sequence *before* sorting: à -> a`)
fields. It could be beneficial to have the option to set these two additional
values globally with an option to override them on a per-table and per-column
basis.

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
