I am unable to get this validator to work with Intl.NumberFormat. Am I missing some options?

Examples

const price = 41.33693
product.price = new Intl.NumberFormat('sv-SE', { style: 'currency', currency: 'SEK'}).format(price)
console.log(product.price) // Returns: SEK 41.34
console.log('Validator:', validator.isCurrency(product.price), { symbol: 'SEK', allow_space_after_symbol: true, })) // Validator: false

Hi @Zyles,
When I run the next code into here

const price = 41.33693
const pPrice = new Intl.NumberFormat('sv-SE', { style: 'currency', currency: 'SEK'}).format(price)
console.log(pPrice) 
// "41,34 kr"

It returns "41,34 kr"

maybe the order has something to do?

Okay... Maybe it formats differently depending on operating system locale?

I am using nodejs on Windows in git bash.
