removing Li if duplicate <a> tag found

Question

Removing <li> if duplicate <a> tag found (after trimming <a> for trailing space from url and text).

I am using seen but the duplicate is still showing. It looks like Dashboard is duplicating but the 2nd Dashboard has a trailing space in the link url and title.

var seen = {};
$('.nav-report-category a').each(function() {
  var txt = $(this).text();
  if (seen[txt]) $(this).closest("li").remove();
  else seen[txt] = true;
});

.nav-report-category {
  border: none !important;
}

.nav-report-category li {
  font-size: 16px;
  padding: 10px 0px;
  width: 110px;
  display: inline-block;
  background-color: rgb(74, 137, 220);
  color: #fff!important;
  margin-right: 5px;
  text-align: center;
  -moz-border-radius: 9px 9px 0px 0px;
  -webkit-border-radius: 9px 9px 0px 0px;
  border-radius: 9px 9px 0px 0px;
  font-color: #fff!important;
}

.nav-report-category li.active {
  background-color: #CB6015!important;
  color: #fff!important;
}

.nav-report-category li a:visited {
  color: #fff!important;
}

.nav-report-category li a {
  color: #fff!important;
}

.nav-report-category li:Hover {
  background-color: #BE3A34;
  text-decoration: none;
}

.tab-desc {
  background-color: rgb(93, 156, 236);
  color: #fff !important;
  padding: 5px;
}

.tab-desc H2 {
  color: #fff !important;
}

Working fiddle.

The main problem comes from the HTML entities you've with the text in your anchors, you must remove/replace them when retrieving the text, your second "Dashboard" text is in the fact Dashboard ‎, so it will never match with Dashboard as key.

Remove them from your JS or remove them from you HTML code, e.g :

var txt = $(this).text().replace(/[^A-Z0-9]+/ig, "");

NOTE 1: Use x.hasOwnProperty(y) to check if an object x has a property y, in your case :

if ( seen.hasOwnProperty( txt ) ){

NOTE 2: As @MasterYoda's comment says Your <li> elements should be children of either <ul> or <ol> not <div>.

var seen = {};
$('.nav-report-category a').each(function() {
  var txt = $(this).text().replace(/[^A-Z0-9]+/ig, "");

  if (seen.hasOwnProperty(txt)) {
    $(this).closest("li").remove();
  } else {
    seen[txt] = true;
  }
});

var seen = {};
$('.nav-report-category a').each(function() {

  var txt1 = decodeURI($(this).text());
  var txt = txt1.replace(/[^a-zA-Z ]/g, "");
  if (seen[txt]) $(this).closest("li").remove();
  else seen[txt] = true;
});
