    The_tags receives an html string formed in this way:

    $html = "<a href="http://my_website.local/tag/tag_one/&quot; rel="tag">tag_one</a>, <a href="http://my_website.local/tag/tag_two/&quot; rel="tag">tag_two</a>";

    In order to replace a tag you may use Clase DOMDocument. For example, you can replace all tags using a replacement word. but do not change the tag’s links. A more useful example can replace some tags by an alias or by a translation. 

    add_filter( 'the_tags', 'my_filter_the_tags');
function my_filter_the_tags( $html)
{
  $dom = new DOMDocument();
  $dom->loadHtml($html);
  $anchors = $dom->getElementsByTagName('a');
  $nb = $anchors->length;
 
  for($pos=0; $pos<$nb; $pos++)
  {
    $anchors->item($pos)->nodeValue = 'any_replacement';
   // check error_log( $anchors->item($pos)->nodeValue); 
  }
   
  $html = $dom->saveHTML();
  return $html;
   
}

    output is this:

    [php]<a href="http://my_website.local/tag/tag_one/&quot; rel="tag">any_replacement</a>, <a href="http://my_website.local/tag/tag_two/&quot; rel="tag">any_replacement</a>

    An easiest way to replace the_tags 

    add_filter( 'the_tags', 'my_filter_the_tags');
function my_filter_the_tags( $html)
{
	$tags = get_tags();
	$out = '';
	foreach ( $tags as $key=>$tag)
        {
            $pos = strpos( $html , $tag->name );
            if (  $pos > 0 ) 
			{
   
                $replace = my_tag_translation($tag->name);
                $out .= '<a href = "'.site_url() .'/tag/' .  $tag->slug . ' " rel="tag" title=""  >' .  $replace . ' ,</a>  ';
           	}
        }
}
