BLOCKED: UX Language Short name Fallback

[srikanthlogic]

At zoom levels 7 and above, the map fallbacks to English which is fallback language of Tamil.

But it would be nice to have a switch to determine how the fallback should happen when short names are missing. (ie, within the language [pure language map] or fallback to short names in fallback language.

ux_language_text_source_short
ux_language_text_source_short_proxy_name

are the functions where this is implemented.

Thanks for your feedback. The upstream vector tiles only have English at low zooms at the moment.

The following upstream issue tracks adding more languages, including alt names (like short):

• 🌍 Low zoom locality names are missing translations + country, region zooms tilezen/vector-datasource#977
• name:short > name_short tilezen/vector-datasource#1102
• Include additional "alt" names tilezen/vector-datasource#1094

In terms of the Cinnabar style, we already default label language and fallback language:

• https://github.com/tangrams/cinnabar-style/blob/gh-pages/cinnabar-style.yaml#L18-L19
• https://mapzen.com/documentation/cartography/api-reference/#language

After the upstream work lands, maybe there is more to do here for functions like ux_language_text_source_short_proxy_name, but that's a little ways off right now.
