get_the_term_list localization

Just implemented a whole bunch of custom taxonomies for Pages and now I would like to show them on my multi-lingual website.

The taxonomies show alright on the English version, but I cannot figure out how to localize the get_the_term_list string.

For example:
<?php echo get_the_term_list( $post->ID, 'size', 'Sizes: ', ', ', '' ); ?>

The string ‘Sizes: ‘ needs to be wrapped some way.

Any solutions?

Thanks in advance
