    Cart popup widget corrupts other info input.

    Tested on Swift 18.0.6 site with the Cart Popup widget installed.

    Give a product an Other Info prompt. E.g. Other Info.

    Add product to cart with "Test 25 " as the other info input.

    Display cart and Other Info now contains "Test £25 ¬ ¦".

    It looks like all characters with the high bit set are being prefixed with an extraneous "".

    The problem seem to be in this fragment of code in sdwidget.min.js that is used to send the product form data to the cart via AJAX:
    This calls the jQuery serialize function and it uses JavaScript's encodeURIComponent to do the actual work. This routine assumes utf-8 encoding where the sign is represented by 2 consecutive hex characters C2 A3.

    However SellerDeck pages are using iso-8859-1 encoding and this uses a single character encoding scheme. E.g. hex A3 for .

    When encodeURIComponent does it's work it expands single character into %C2%A3, passes it to the Shopping Cart via AJAX and our utf-8 pages subsequently display that as £.

    The solution is to replace jQuery .serialize() with an iso-8859-1 compatible one. I found such a fix on the jQuery Forum

    Edit sdwidget.min.js and add the following at the beginning:
    // based on jQuery Forum -
    $.fn.serializeISO8859 = function(){
    	var s = []; 
    	$.each( this.serializeArray(), function( i, v ){s.push(\+/g, '%2B') + "=" + v.value.replace(/\+/g, '%2B'));});
    	return s.join("&").replace(/%20/g, '+');
    And look for the fragment of code:
    and replace with:
    For completeness do the same to file sdwidget.js.

      Thanks Norman, that's extremely helpful as always. I've raised a bug for this, ref. SDE-748
