Some Wiktionaries have custom namespaces, and namespace that don't exist on all the Wiktionaries. How exactly do we deal with those?
- Is it a problem if some namespaces are specific to one Wiktionary?
- Do we store the links in Wikidata as well?
- Can the Citations namespace be linked with Cognate?
Another similar problem: pages about a single punctuation character such as ":". They are solved with a custom URL: https://en.wiktionary.org/wiki/Unsupported_titles/Colon which is different in each language https://fr.wiktionary.org/wiki/Titres_non_pris_en_charge/:
What's the best way to provide centralized links for these?
