x/text/currency: position of the ISO code or sign in amounts

[arvenil]

    currencyCode = "PLN"
    unit, _ := currency.ParseISO(currencyCode)
    p := message.NewPrinter(language.Polish)
    amount := float64(100)
    p.Print(currency.Symbol(unit.Amount(amount)))

The result is zł 100 but I would expect 100 zł.

I would expect 100 zł but maybe there is "other" library/func/method that handles order?
Or if this is on TODO list, any idea how could I workaround the problem?

Looks like position is hard coded :/ https://github.com/golang/text/blob/3fe38e9bb80a6f7a308692511ffdbae1537f0505/currency/format.go#L77-L89

I would like to work on this but I'm not sure how to find the correct position for the currency symbol. Can someone help me out?

[arvenil]

@jarifibrahim Do you mean this?

1. https://en.wikipedia.org/wiki/ISO_4217#Position_of_ISO_4217_code_in_amounts
2. http://publications.europa.eu/code/en/en-370303.htm#position

Note that, as illustrated, the order is determined not by the currency, but by the native language of the document context.

x/text/currency is missing number formats, which are provided by CLDR.

Here's how such a list would look: https://github.com/bojanz/currency/blob/master/data.go#L795
