Backbone navigate - url encode in different language with diacritics

Nobody has claimed this yet.

I have a search form that redirects the user to `search/thetermusersearched` where `thetermusersearched` is the exact value he entered. All this with the navigate function provided by Backbone.

This is all fine when I use strings in English (masa de calcat), but when I add diacritics in the input (masă de călcat) I get the route function fired twice.

The problem I have is in Firefox and Safari (the later in Mac and iOS)

I tried using `encodeURI` and `encodeURIComponent` when I use the `navigate`, but no success.

JS

```
var R = Backbone.Router.extend({
routes: {
'results/:query': 'results'
},
results: function(query) {
alert('Route triggered: ' + decodeURIComponent(query));
}
});
var myR = new R;
Backbone.history.start();

$(function(){
$('a').on('click', function(e){
e.preventDefault();
var href = $(this).data('string');
href = 'results/' + encodeURIComponent(href);
console.log(href);
myR.navigate(href, {trigger: true});
})
})
```

Any thoughts on this?

Reproduce the provided fiddle in Firefox and Safari, then trace Backbone.Router, Backbone.history.start, and myR.navigate with the diacritic-containing route. Determine why the results callback fires twice; done means the encoded query triggers the route once and still displays the decoded search term.
