Ignore accent when using search menu (input)

Question

I created a input search and a list (side menu) below, when I do the search is ok, but I’m in trouble when any <li> has voice with accentuation.

How could I implement a regular expression to help me?

$(function() {
    $("#buscar-menu").keyup(
        function() {
            var menuBuscado = $(this).val().toUpperCase();
                $(".menu-busca li").css("display", "block");
                $(".menu-busca li").each(function() {
                            if ($(this).text().toUpperCase().indexOf(
                                    menuBuscado.toUpperCase()) < 0) {
                                $(this).css("display", "none");
                            }
                });
        });
});

It is possible to create a function for this particular case, which would remove the accents only in the query, in the example below I entered a function called removeAcento that will receive a parameter(string) and return the same string without the accents, just do this in the input typed and the text recovered within the function each jquery.

Making it look like this:

function removeAcento(text){       
    text = text.toLowerCase();                                                         
    text = text.replace(new RegExp('[ÁÀÂÃ]','gi'), 'a');
    text = text.replace(new RegExp('[ÉÈÊ]','gi'), 'e');
    text = text.replace(new RegExp('[ÍÌÎ]','gi'), 'i');
    text = text.replace(new RegExp('[ÓÒÔÕ]','gi'), 'o');
    text = text.replace(new RegExp('[ÚÙÛ]','gi'), 'u');
    return text;                 
}

$(function() {
  $("#buscar-menu").keyup(
    function() {
      var menuBuscado = removeAcento($(this).val().toUpperCase());
      $(".menu-busca li").css("display", "block");
      $(".menu-busca li").each(function() {
      if (removeAcento($(this).text()).toUpperCase().indexOf(
        menuBuscado.toUpperCase()) < 0) {
        $(this).css("display", "none");
      }
    });
  });
});
