Serbian can be written in Latin or Cyrillic,

Interestingly, every Latin character can actually be mapped to
one Cyrillic character, and the other way around,
so you could write a script to turn one po-file into the other.
But most practical is to have two locales with names
sr@Latn and sr@Cyrl. These are then two character sets
for the same language. So they should end up together
under the same language in a translation domain.
The best way for an integrator to choose which one to use,
is to add an environment variable 'zope_i18n_allowed_languages'
and let this contain either sr@Latn or sr@Cyrl.
