This JSON file (script-lang-match.json) matches scripts (alphabets) to their languages. ISO-15924 is used for the script codes. The languages codes are based on ISO-639-3.
Note that the Latin script is not included, because it is the default script.
Example for the Tamil script:
{
"id": "Taml",
"name": "Tamil",
"notes": null,
"langs": ["tam", "oty", "kev", "bfq", "iru", "pcg", "saz"]
},The "id" field is the ISO-15924 code for the script. The "name" field is the name of the script. The "langs" field is an array of language codes based on ISO-639-3. In the case of the Tamil script it is the Tamil language (tam), Old Tamil (oty), Kanikkaran (kev) and four other languages.
