Problem with accents and the content_filter rendering

Hi !
I noticed on my whole site that when I have an amazon link, all the accents and special characters are affected by wrong charset. It doesn’t affect page title part.

Check https://frenchw.net/test/ for example.
Title is “TEst et détails dipl?me” and is rendered correctly
Content contains “Détail de l’offre proposée” and is rendered ‘D??TAIL DE L’OFFRE PROPOS??E’ (if’s in H3)
it’s because I have just after a simple link:

<a href="https://www.amazon.co.uk/XCSOURCE-10pcs-Cleaning-Cameras-DC580/dp/B00TF9AIF4/ref=as_li_ss_il?crid=GDR8TUWFJRRM&keywords=apsc+sensor+cleaning+kit&qid=1571894469&sprefix=apsc+senso,kitchen,147&sr=8-9&linkCode=li2&tag=frw-blog-21&linkId=cf78e38798c1ab389c36fb89376e461e" target="_blank" rel="noopener noreferrer"><img border="0" src="//ws-eu.amazon-adsystem.com/widgets/q?_encoding=UTF8&ASIN=B00TF9AIF4&Format=_SL160_&ID=AsinImage&MarketPlace=GB&ServiceVersion=20070822&WS=1&tag=frw-blog-21"></a><img src="https://ir-uk.amazon-adsystem.com/e/ir?t=frw-blog-21&l=li2&o=2&a=B00TF9AIF4" width="1" height="1" border="0" alt="" style="border:none !important; margin:0px !important;">

If I use the new Guttenberg tag, it’s OK but I can’t use it everywhere.

<!-- wp:amazon-associates-link-builder/aalb-gutenberg-block {"shortCodeContent":"[amazon_link asins='B01JJ1VDQK' template='FW-ProductAd' store='frw-blog-art-21' marketplace='FR' link_id='c814875f-8a6e-4d93-8f84-c641af82fbcc']","searchKeyword":"B01JJ1VDQK card"} /-->

CAUSE

after searching all around, I found the cause. It’s in /plugins/amazon-associates-link-builder/rendering/content_filter.php
A regex searches the page content for amazon urls and makes some changes.
In this file, and to match the example just above, If I change in
private static $AMAZON_DOMAINS = array(......
… the “amazon.co.uk” string to… lets say… “amazon.com.uk” then regex doesn’t match and my page is rendered correcty.

I’m not a good php developper and I can’t find easily why this code changes the accents contened in the page:

        //Remove noreferrer form amazon anchor links
        foreach ( $anchor_node_list as $anchor_node ) {
            if ( $this->has_amazon_link( $anchor_node ) ) {
                $this->remove_noreferrer( $anchor_node );
                $content_updated = true;
            }
        }

        return $content_updated ? $document->saveHTML() : $content;

I’m available for better testing
best regard.
