Filtering datatables on Non English data

prassad2007

I'm using the datatables plugin to display list of records by using ajax source. The results have non-english data like 'Informática','Médico' etc. I am able to filter by using the default search box but not based when searching based on that particular field(column). Here's my code
[code]
var $dTable = $('#filter_Table').dataTable( {
"bProcessing": true,
"sAjaxSource": '/get_service_data',
"sPaginationType": "full_numbers",
"aaSorting": [[ 0, "desc" ]],
"aoColumns": [null,null,null,null,null,null,null,null,{ "bSortable": false },{ "bSortable": false }, null]

} );
$("#search_field1").keyup( function () {
/* Filter on the column (the index) of this element */
$dTable.fnFilter(this.value, 2);
} );
$("#search_field2").keyup( function () {
/* Filter on the column (the index) of this element */
$dTable.fnFilter(this.value, 10);
} );

[/code]
Can anyone please suggest or let me know if I'm missing anything here.
