How to sort greek letters/symbols JavaScript

I have managed to sort an array of objects by element name 'post_api_name' however some of these elements start with a Greek symbol (e.g. α-β Arteether). How can I convert these symbols to be placed alongside 0-9 and not Z+1.

RESULT.sort(function(a, b) {
var textA = a.post_api_name.toUpperCase();
var textB = b.post_api_name.toUpperCase();
return (textA < textB) ? -1 : (textA > textB) ? 1 : 0;
});


For clarity, the current sorted results show as:

a
b
c
α

I am hoping to achieve:

α
a
b
c

Answer

You can try sorting using the Greek locale. You would want to test with more cases as I have no idea what other sorting rules could apply. Browser support for localeCompare is still relatively cutting edge (IE11). Maybe you can find a poly-fill.

Maybe more preferably you might just have a list of Greek characters that you support and replace them with one of the characters between 9 and A for sorting purposes (:;<=>? or @).

var items = ['a', 'b', 'c', 'α', '9', '4', '1']

items.sort(function(a, b){
  return a.localeCompare(b, 'el');
});

console.log(items);
