Hey team! Please add your planning poker estimate with Zenhub @cesarcosta99 @lovo-h @rafaelzaleski @reykjalin @ricardo

It looks like things are a bit different than the time this has been reported.

the currency preview is producing incorrect previews given my configurations for rounding rules and price charming.
...
In the screen shot above, the preview price should be 115 [XPF]
...
The preview price should be ¥140

The values in the currency preview seem correct now and match what's expected.

Pacific Franc	Japanese Yen

For the Pacific Franc (XPF) the currency symbol is incorrectly placed, and the wrong symbol.

The currency codes are retrieved from WC core here. And the get_woocommerce_currency_symbols function documents how the symbols are defined as follows:

Currency symbols and names should follow the Unicode CLDR recommendation https://cldr.unicode.org/translation/currency-names-and-symbols

I'm not familiar with this currency and the countries that use it, but according to the Symbols guidelines linked above, the XPF currency would fall into item 1.3, which says:

1. If a symbol is not widely recognized around the world
   3. ...use the international currency symbol (eg ILS). This can be done just by omitting the translation

I also did some research and Wikipedia (and a few other sites) indicate that the symbol of the CFP franc currency is F.

The Fr symbol has been defined 6 years ago, but if I'm reading correctly the guidelines WC core is based on, the symbol should be changed to XPF, as suggested in this issue. The formatting of the value would be XPF 100. However, I'd like to have another pair of eyes to confirm my reasoning. Looping in @bborman22 to take a look when you have a chance.

Now, moving to the store frontend.

On the front end of the store, the prices appear to be calculated correctly, however for the XPF currency, they're missing the coma separator for thousands, and also using the incorrect symbol (Trailing Fr, rather than the correct XPF preceding with a space) I tested for this using Yen, and the coma was placed correctly, so it looks like it might just be limited to XPF

The trailing Fr seems to have been fixed, but the comma separator is still an issue and doesn't match what's seen in the currency preview. Regarding the XPF symbol, I'll wait the outcome of the aforementioned symbol discussion.

With the new changes applied in the currency the formatting in the preview is going to be XPF1,234 (without a space between symbol and value). That's going to happen because, in the currency preview, the value is formatted based on the store currency formatting [ref].

I have conflicting perspectives about this approach because, as much as I understand this being easier for the store owner to understand the conversion, it's not representing accurately how the currency is going to be presented. @bborman22, I would appreciate a second opinion here to decide if we should keep this behavior, or change it to display the actual currency formatting.

Sorry I don't have a super strong understanding of the difference between this preview and the actual display, but I would expect them to match. This conflict between using store currency formatting in the admin has been a consistent problem I'm looking to get addressed.

Given the explicit context here that this is a preview of how it will be displayed, I would say we should use the front-end display rules if we can?
