var collator = new Intl.Collator();
var langCollator = new Intl.Collator('en');

Tests:

Intl.Collator.compare
const sortTagsBySetId = (a, b) => { return collator.compare(a.name, b.name); }; values.concat().sort(sortTagsBySetId);
localCompare
const sortTagsBySetId = (a, b) => { return a.name.localeCompare(b.name); }; values.concat().sort(sortTagsBySetId);
Intl.Collator.compare with lang
const sortTagsBySetId = (a, b) => { return langCollator.compare(a.name, b.name); }; values.concat().sort(sortTagsBySetId);
