Facebook sharing URL not showing special characters ( diacritics, breve)

Hi!

I have a problem related to sharing a post from my blog to Facebook.

My URL should look like this actually:
spranceanaluidostoievski.ro

The character with a breve is : a. But when I share a post I want the link displayed in Facebook to contain spranceanaluidostoievski.ro and not xn--sprnceanaluidostoievski-k6b.ro.
How can I do that?

I tried already to edit the functions.php on the Theme Editor with the following:

function ow_ogurl_yoast_filter( $ogurl ){
return str_replace( ‘xn--sprnceanaluidostoievski-k6b’, ‘spranceanaluidostoievski’, $ogurl );
}

But somehow it does not work :(. I need help and suggestions

With the Facebook debugger option I can see:
— Jetpack Site Verification Tags –><!– This site is optimized with the Yoast SEO plugin v11.5 – https://yoast.com/wordpress/plugins/seo/ –><link rel=”canonical” href=”https://spr%C3%A2nceanaluidostoievski.ro/ioana-parvulescu-intoarcere-in-secolul-21/”&gt;

<meta property=”og:site_name” content=”Spranceana lui Dostoievski”>

How can I manipulate the og:url sent ?
