Major Change to Large Merchant Services: UTF-8 encoding is required starting Feb 14, 2011
Beginning 2011-02-14, Large Merchant Services will require all input files to be UTF-8 encoded. Other encodings (e.g. ISO-8859-1) will not be rejected by the system, but some characters may not be rendered correctly on the View Item page.
Please make the required changes in your application.
