During the development of a multilingual Ubercart store I found a couple of non-multilingual strings.
These were Ubercart variables which provide customizations:
- Order statuses (Completed, Canceled, ... etc.)
- Address fields (First name, Last name, ... etc.)
- Product attributes
The first two category of strings are available in pot files but these aren't stored in the {variable} table and thus cannot be converted to a multilingual variable via i18n module. For example Order status real values reside in {uc_order_statuses} and it can only get value for one language.

Is there any other way to make these working without re-writing for ex. the uc_order.module corresponding functions?

Forgot to mention that I'm talking about Drupal 5.x here.
