[Mathieu, 2017/01/05 19:06:15]

nit: the <ex> doesn't look like the final result, shouldn't it be USD 12.34?

Also, are there plans to add the $ sign?

[anthonyvd, 2017/01/05 19:12:40]

The full formatted text will be something like "Total USD $12.34". Since the
"symbol+amount" part is the output of the currency formatter, we only need 3
parts: "Total" (label), "USD" (currency code), and "$12.34" (formatted total
amount). This is what the 3 <ex>'s here are conveying.

The issue, as you noticed, is that the c++ formatter isn't implemented so the
code consuming this format string isn't passing it the correct last piece
currently. Once it's implemented, the code using this format string will be
fixed, the <ex> will be correct, and the $ sign (or other currency symbols) will
be present!
