I don't get what ur sayin bout the 403 error but there's no greek language
enabled so I don't know where are you clicking "to go for Greek".
Portuguese is a non oficial language and users r translating it in the
English wiki but naming it in Portuguese. I don't know exactly how they deal
with the non English characters....
Take a look here -->

You can access that page thru this one
http://trisquel.info/en/wiki/documentation clicking for the Portuguese
translation mentioned on the page content.
Here u kn c the work on the All Manuals section

You can do the same for Greek.
Kisses to your hair
