[Koha] original title in OPAC

[Giuseppe Angilella]

Hi,

how do I display the title in the original language of a translated item 
in the OPAC? This should be contained in the MARC field 765$t (which is 
normally hidden).

(A varying form of title, as recorded in 246$a, is shown as "Other 
title".)

Should 765$t be somehow linked to the subtitle field?

Many thanks.

Giuseppe.
