Intl.NumberFormat space character does not match

Question

I\'m running into an issue where Intl.NumberFormat is formatting the space character in some way that is different from what Jest is expecting. Tests against t

Answer 1

NumberFormat use small non-breaking space (\u202f) for thousand separator and normal non-breaking space beforece currency (\xa0)

  expect(new Intl.NumberFormat("fr-FR", {
    style: "currency",
    currency: "EUR",
  }).format(126126)).toBe("126\u202f126,00\xa0€")

Answer 2

'11 111.11'.split('').map(x => console.log((x.charCodeAt(0))))

Yields "32" for the space character which is a normal space.

new Intl.NumberFormat('fr-CA').format(11111.11).split('').map(x => console.log((x.charCodeAt(0))))

Yields "160" for the space character, which is a non-breaking space.

To make these tests pass, you need to add the non-breaking space UTF-16 (\xa0) character code into the assertion.

expect(formatCurrency(24555.55, 'fr_CA', true)).toBe('24\xa0555,55 $');
