curent language token on block body what is the token used to get the curent language, I want to use this token on a link in the block body, like that:

&lt;a href="/[curent-language]/about-us"&gt;About us&lt;/a&gt;


I find this token [site:url] is good, but in default language the link become //about-us two slashes, otherwise /fr/about-us in the french language(good).
try &lt;a href="/[node:source:language]/about-us"&gt;About us&lt;/a&gt;
