This ticket can never be really up-to-date, since it is not updated automatically. It is an initial inventory of how languages behave in Wikidocumentaries, and intended to help discover errors.
This listing in unfinished but suggests that
* rtl support is needed for some languages
* the fonts do not support all languages
* not all autonyms are satisfactory > better source for them may be needed
* 3-letter language codes are truncated in the router
* the router fails altogether with language codes with a hyphen
* it is unclear if there are discrepancies between resources in the use of language codes > needs to be explored
