Important Improvements

1: for the "translations" json Key, you have to support the "United Nations Officialy Supported Languages" , which contains the Arabic ("ara") language...

2: I think "demonyms" json key name should be "nationality"! and the "region" json key should be "continent" and "subregion" should be "region".

3: this json file:
https://raw.githubusercontent.com/mledoze/countries/master/countries.json
is about 1.21 MB in sized, you have to provide a compressed version of the files, that should be inline-json, and make it's name countries-compressed.json for example, like this example of data:
[{"name":{"common":"Aruba","official":"Aruba","native":{"nld":{"official":"Aruba","common":"Aruba"},"pap":{"official":"Aruba","common":"Aruba"}}},"tld":[".aw"],"cca2":"AW","ccn3":"533","cca3":"ABW","cioc":"ARU","independent":false,"status":"officially-assigned","unMember":false,"currencies":{"AWG":{"name":"Aruban florin","symbol":"\u0192"}},"idd":{"root":"+2","suffixes":["97"]},"capital":["Oranjestad"],"altSpellings":["AW"],"region":"Americas","subregion":"Caribbean","languages":{"nld":"Dutch","pap":"Papiamento"},"translations":{"ces":{"official":"Aruba","common":"Aruba"},"deu":{"official":"Aruba","common":"Aruba"},"est":{"official":"Aruba","common":"Aruba"},"fin":{"official":"Aruba","common":"Aruba"},"fra":{"official":"Aruba","common":"Aruba"},"hrv":{"official":"Aruba","common":"Aruba"},"hun":{"official":"Aruba","common":"Aruba"},"ita":{"official":"Aruba","common":"Aruba"},"jpn":{"official":"\u30a2\u30eb\u30d0","common":"\u30a2\u30eb\u30d0"},"kor":{"official":"\uc544\ub8e8\ubc14","common":"\uc544\ub8e8\ubc14"},"nld":{"official":"Aruba","common":"Aruba"},"per":{"official":"\u0622\u0631\u0648\u0628\u0627","common":"\u0622\u0631\u0648\u0628\u0627"},"pol":{"official":"Aruba","common":"Aruba"},"por":{"official":"Aruba","common":"Aruba"},"rus":{"official":"\u0410\u0440\u0443\u0431\u0430","common":"\u0410\u0440\u0443\u0431\u0430"},"slk":{"official":"Aruba","common":"Aruba"},"spa":{"official":"Aruba","common":"Aruba"},"swe":{"official":"Aruba","common":"Aruba"},"urd":{"official":"\u0627\u0631\u0648\u0628\u0627","common":"\u0627\u0631\u0648\u0628\u0627"},"zho":{"official":"\u963f\u9c81\u5df4","common":"\u963f\u9c81\u5df4"}},"latlng":[12.5, -69.96666666],"landlocked":false,"borders":[],"area":180,"flag":"\ud83c\udde6\ud83c\uddfc","demonyms":{"eng":{"f":"Aruban","m":"Aruban"},"fra":{"f":"Arubaise","m":"Arubais"}}}, etc ...]

when I inline this json file I got 669 KB json file and this is much better for websites and apps who is going to use these data ..

thx

about the "languages" json key, can we add "isRTL": true | false to determine if this language is from Right to left or not?
