Hi Strainu,
There is some documentation about this here:
Briefly, we've taken a datadump of ISO-3166-2 data from
commondatahub.org, which we use to provide the mapping from ISO-3166-2 region codes to their English names. We have put together a script that then takes all of those names and attempts to auto-'translate' them by checking the name against the interwiki language links API.
We can easily override the automatic 'translations' that we have. If you'd like to do it yourself, you should fork the repository on github, follow the instructions in the readme file, and submit a pull request:
Alternatively, you can file a bug in bugzilla with a mapping of ISO-3166-2 region codes to regional names, and we can get the translations added when we are able.
All of the WMF staff will be busy in our annual all-staff meetings for the rest of the week, so forgive us if we are unable to respond as quickly as usual.
Thanks!
Arthur
