    Description

      Got this on Qt.locale("pl_PL")

      For large numbers in standard notation, function Number.FromLocaleString() returns Invalid Format. The core issue seems to be that it doesn't handle well multiple separate spaces within one number
      To reproduce:

      Number.fromLocaleString(Qt.locale(),"9 999 998,20");    //exception Invalid Format
Number.fromLocaleString(Qt.locale(),"9999 998,20");    //OK

      For large numbers, the conversion also doesn't work both ways.

      Minimal code to reproduce:

      import QtQuick 2.15
import QtTest 1.0

TestCase {
    name: "NumberToLocaleString"

    function test_case1() {
        Number.fromLocaleString(Qt.locale("pl_PL"),"9 999 998,20");    //exception Invalid Format
        verify(false);
    }
    function test_case2() {
        Number.fromLocaleString(Qt.locale("pl_PL"),"9999 998,20");    //OK
        verify(true);
    }
    function test_case3() {
        var num = Number(9999998.20).toLocaleString(Qt.locale("pl_PL"));
        console.log(num)
        Number.fromLocaleString(Qt.locale(),num);    //exception Invalid Format
        verify(true);
    }
}
