Magento 2 How to customize Currency symbol and format based on locale
<p>I want to change currency format pattern, currency symbol and currency symbol position programmatically. I found some data in folder vendor\magento\zendframework1\library\Zend\Locale\Data.</p>

<p>For example if I change the format in <code>fr_FR.xml</code> by following code its is reflecting in frontend.</p>

<pre><code>&lt;numbers&gt;
        &lt;currencyFormats numberSystem="latn"&gt;
            &lt;currencyFormatLength&gt;
                &lt;currencyFormat type="standard"&gt;
                    &lt;pattern&gt;¤ #,##0.00&lt;/pattern&gt;
                &lt;/currencyFormat&gt;
                &lt;currencyFormat type="accounting"&gt;
                    &lt;pattern&gt;¤ #,##0.00;(¤ #,##0.00)&lt;/pattern&gt;
                &lt;/currencyFormat&gt;
            &lt;/currencyFormatLength&gt;
            &lt;unitPattern count="one"&gt;{0} {1}&lt;/unitPattern&gt;
            &lt;unitPattern count="other"&gt;{0} {1}&lt;/unitPattern&gt;
        &lt;/currencyFormats&gt;
        &lt;currencies&gt;
            &lt;currency type="GBP"&gt;
                &lt;displayName&gt;livre sterling&lt;/displayName&gt;
                &lt;displayName count="one"&gt;livre sterling&lt;/displayName&gt;
                &lt;displayName count="other"&gt;livres sterling&lt;/displayName&gt;
                &lt;symbol&gt;£&lt;/symbol&gt;
            &lt;/currency&gt;
        &lt;/currencies&gt;
&lt;/numbers&gt;
</code></pre>

<p>But I want to know how to override the default fr_FR.xml (vendor\magento\zendframework1\library\Zend\Locale\Data\fr_FR.xml)</p>

<p>Kindly let me know if anyone knows the way to do.</p>
