JQuery datatablejs turkish character search problem

Question

I have a jquery datatablejs. I list items. I want to search something in search. But when i enter İ it finds only İ chars. I want to find also i chars. Like I-ı Ü-ü.

I searched lots of sites/docs but find anything.

This link below defines turkish chars for sorting. Can we use this for searching? Other problem is or we can say my constraint is I can't change datatable's original data. I can't replace İ to i or i to İ.

Note: I am getting data with ajax from mvc controller. I do not get json data. I get model object.

I found a solution and it work without any problem.

Here is the solution:

I call this function:

https://jsfiddle.net/s39o8pdu/1/

jQuery.extend( jQuery.fn.dataTableExt.oSort, {
  'locale-compare-asc': function ( a, b ) {
     return a.localeCompare(b, 'cs', { sensitivity: 'case' })
  },
  'locale-compare-desc': function ( a, b ) {
     return b.localeCompare(a, 'cs', { sensitivity: 'case' })
  }
})

jQuery.fn.dataTable.ext.type.search['locale-compare'] = function (data) {
    return NeutralizeAccent(data);
}

function NeutralizeAccent(data)
{
  return !data
      ? ''
        : typeof data === 'string'
        ? data
        .replace(/\n/g, ' ')
        .replace(/[éÉěĚèêëÈÊË]/g, 'e')
        .replace(/[šŠ]/g, 's')
        .replace(/[čČçÇ]/g, 'c')
        .replace(/[řŘ]/g, 'r')
        .replace(/[žŽ]/g, 'z')
        .replace(/[ýÝ]/g, 'y')
        .replace(/[áÁâàÂÀ]/g, 'a')
        .replace(/[íÍîïÎİÏ]/g, 'i')
        .replace(/[ťŤ]/g, 't')
        .replace(/[ďĎ]/g, 'd')
        .replace(/[ňŇ]/g, 'n')
        .replace(/[óÓ]/g, 'o')
        .replace(/[úÚůŮ]/g, 'u')
        : data
}

var table = $('#example').DataTable({
    columnDefs : [
     { targets: 0, type: 'locale-compare' },
  ]
})

 $('#example_filter input').keyup(function () {
    table
    .search(
      jQuery.fn.dataTable.ext.type.search.string(NeutralizeAccent(this.value))
    )
    .draw()
 })
 

So good luck who has this problem. If you have any problem ask me. I know how to solve this problem now.

Like andrewjames said on the answers we solve this problem with Accent neutralise.
