Temporary fix as follows:
In wp-e-commerce\wpsc-components\theme-engine-v1\helpers\shipping.php
look for the wpsc_shipping_quote_name() function at line 66.

Replace it with this:

function wpsc_shipping_quote_name() {
   global $wpsc_cart;

  $fix = str_replace("& a m p ; l t ; sup & a m p ; g t ; & a m p ; # 1 7 4 ; & a m p ; l t ; / s u p & a m p ; g t ;", "<sup>& reg ;</sup>", $wpsc_cart->shipping_quote['name']);
  $fix = str_replace("& a  m p ; l t ; s u p & a m p ; g t ; & a m p ; # 1 5 3 ; & a m p ; l t ; / s u p & a m p ; g t ;", "<sup>& trade ;</sup>", $wpsc_cart->shipping_quote['name']);

  $wpsc_cart->shipping_quote['name']  = $fix;

   return apply_filters( 'wpsc_shipping_quote_name', $wpsc_cart->shipping_quote['name'] );
}

Just take the spaces out of the search strings – every time I posted the actual code it kept converting the characters.
