Multi currency site show a 0 price only in the magento2 checkout page

Question

I installed a fresh version of magento2 with the simple data, test the payment in USD using the cash on delivery, and the payment was fine.

I added more currencies KWD, EGP, and EUR. Then configure the rates. After that, I tested the payment with EUR and it was fine. I tested the payment with EGP/KWD but the price is 0 only on the checkout page. I got that the attached image

The change of the currency works fine for all pages including orders in the admin pages.

Answer 1

I know is late but for feature search.

Same issue here. In my case was from Currency Symbols (vendor/magento/module-directory/Model/Currency.php) method (getOutputFormat) when has to give format for price-utils.js

In case of EURO or USD the $formatted is something like this: $0.00 or €0.00 in case you have EGP the $formatted is EGP 0.00

$formatted = $this->formatTxt(0); 
RESULT: $0.00, €0.00, EGP 0.00
$number = $this->formatTxt(0, ['display' => \Magento\Framework\Currency::NO_SYMBOL]); 
RESULT: 0.00, €0.00, EGP0.00
return str_replace($this->trimUnicodeDirectionMark($number), '%s', $formatted); 
RESULT: $%s, %s, EGP 0.00

Issue in trimUnicodeDirectionMark on

preg_match('/^(\x{200E}|\x{200F})/u', $string, $match)

Answer 2

Yes, Many times this issue is a big problem. I found below file is responsible for this issue.

vendor/magento/module-directory/Model/Currency.php

Solution: https://github.com/magento/magento2/pull/33966/commits/82c1a4d1137f747b9551e7d4d87106bf2c726b9e

You need to update your core Currency.php file. You can not overwrite this core file in your custom module. I tried but it's not working. So I created a custom patch for it.
