Breezewiki doesn't support wikis that have translations into other
languages right now.

For instance, if we take two urls: one is the English language version
of the MLP wiki, and the other is the Spanish version, then the Spanish
URL has an additional directory '/es' in the pathname for the Spanish
version:

https://mlp.fandom.com/wiki/My_Little_Pony_Friendship_is_Magic_Wiki
https://mlp.fandom.com/es/wiki/My_Little_Pony:_La_Magia_de_la_Amistad_Wiki

If we convert them into their respective Breezewiki URLs, we get this:

https://breezewiki.com/mlp/wiki/My_Little_Pony_Friendship_is_Magic_Wiki
https://breezewiki.com/mlp/es/wiki/My_Little_Pony:_La_Magia_de_la_Amistad_Wiki 

The English version works fine, but the Spanish version gets a Not
Found error.

Moreover, Having a built-in language switcher for every page, like how
Fandom has it would be neat, but just getting the multilingual pages
working for now would be good enough.
