I did not know that one. Where is it used?

[BoboTiG]

It is only used in french pages? I would more thinking of it as a global variable.

It's used on this page : https://fr.wiktionary.org/wiki/apr._J.-C. (and this page only I believe)

[BoboTiG]

Hm that page does not exist.

https://fr.wiktionary.org/wiki/apr._J.-C.

It seems GH has some issue displaying the link.

Let's add this special code, we could do it from utils.py::clean() I think.
