Prestashop Add canonical and hreflang for multi-language website

We can add the cannonical and hreflang tags on prestashop at the header.tpl template file. The template files are under theme/yourthemename folder.

Special Character (Zero-width joiner)

The zero-width joiner (ZWJ) is a non-printing character used in the computerized typesetting of some complex scripts such as the Arabic script or any Indic script. When placed between two characters that would otherwise not be connected, a ZWJ causes them to be printed in their connected forms. It means it doesnot take additional space. It is   &zwj; Useful when we need to output some html that don't need space. In some editors like tinymce, when we put the html that don't contain space then it will not save that html and will remove it from editor. For eg: <a href=".."></a> When we try to save the above html on tinymce editor, it will remove it from the content because it doen't have any character inside it. So, to overcome that problem we can use this special zero-width joiner character in between. It is a character that don't output extra space.  <a href="..">&zwj;</a> Happy coding!!!
