How to Decode CURL Response Correctly ?

Using:

decodeURIComponent(escape(datas[i].display_name))

I have an error and escape() is deprecated, I think the problem is with the Î character \u017D

And using a decode() function

    function decode(s) {
        for (var a, b, i = -1, l = (s = s.split("")).length, o = String.fromCharCode, c = "charCodeAt"; ++i < l;
            ((a = s[i][c](0)) & 0x80) &&
            (s[i] = (a & 0xfc) == 0xc0 && ((b = s[i + 1][c](0)) & 0xc0) == 0x80 ?
                o(((a & 0x03) << 6) + (b & 0x3f)) : o(128), s[++i] = "")
        );
        return s.join("");
    }

it works better but I still have a problem with some characters 

nominatim.jsx

(function(thisObj) {
    function decode(s) {
        for (var a, b, i = -1, l = (s = s.split("")).length, o = String.fromCharCode, c = "charCodeAt"; ++i < l;
            ((a = s[i][c](0)) & 0x80) &&
            (s[i] = (a & 0xfc) == 0xc0 && ((b = s[i + 1][c](0)) & 0xc0) == 0x80 ?
                o(((a & 0x03) << 6) + (b & 0x3f)) : o(128), s[++i] = "")
        );
        return s.join("");
    }

    buildUI(thisObj);

    function buildUI(thisObj) {
        var proj = app.project;
        var thisComp = proj.activeItem;
        var palette = (thisObj instanceof Panel) ? thisObj : new Window("palette", "Nominatim", undefined, {
            resizeable: true
        })
        palette.alignChildren = ["left", "center"];
        palette.margins = 5;
        palette.spacing = 2;

        var edittext1 = palette.add('edittext {properties: {name: "edittext1"}}');
        edittext1.preferredSize.width = 640;

        var listbox1 = palette.add("listbox", undefined, undefined, {
            name: "listbox1",
            items: []
        });
        listbox1.preferredSize.width = 640;

        if (palette instanceof Window) {
            palette.center();
            palette.show()
        } else {
            palette.layout.layout(true);
            palette.layout.resize()
        }

        edittext1.addEventListener("keydown", function(e) {
            palette.remove(listbox1);
            var arr = [];
            if (e.keyName == 'Enter') {
                var url = "https://nominatim.openstreetmap.org/search?q=" + encodeURI(this.text) + "&format=json&polygon=1&addressdetails=1";
                var datas = JSON.parse(system.callSystem("curl -s \"Accept: application/json\" \"" + url + "\""));
                for (var i = 0; i < datas.length; i++) {
                    //arr.push(decodeURIComponent(escape(datas[i].display_name)))
                    arr.push(decode(datas[i].display_name))
                }
                listbox1 = palette.add("listbox", undefined, undefined, {
                    name: "listbox1",
                    items: arr
                });
                listbox1.onChange = function() {
                    var proj = app.project;
                    var thisComp = proj.activeItem;
                    if (thisComp.numLayers && thisComp.layer(1) instanceof TextLayer) {
                        thisComp.layer(1).text.sourceText.setValue(this.selection.text);
                    } else {
                        thisComp.layers.addText(this.selection.text)
                    }
                }
            } else {
                listbox1 = palette.add("listbox", undefined, undefined, {
                    name: "listbox1",
                    items: []
                });
            }
            listbox1.preferredSize.width = 640;
            palette.layout.layout(true);
        });
    }
