Amir, In Romanian, this kind of possible, but highly unlikely problem is called "drob de sare" (salt stone). I'll let you use your language skills to find out why :) Let the community be and find their own ways to deal with the problem, if it ever becomes a real one. If one really wants to link to the sanskrit Wikipedia, it can do so using [[:w:sa:...]]. Bugs in Pwb can be solved if you log them - but does Tyap has any robots today? No need to have users in a new language write in English just because some problems might occur in certain very particular scenarios. My 2c, Andrei Pe sâmbătă, 4 iunie 2022, Amir E.

They are not very likely to be inserted into articles, but still, it's somewhat conceivable. I also noticed that it confuses Pywikibot in some ways. And I can imagine other subtle bugs that it will cause. "Category" to something else. No—they want to use "Sa". It's legitimate not to want to change the word for a technical reason. wikitext, but they would like to see "Sa:" in the title of category pages. I'm not sure that it's possible: as far as I know, the namespace name definition in MessagesKcg.php will be used for both things, and if Visual editor is used to add categories, it will add "[[Sa:". Bots or gadgets can be used to replace it to "Category", but is looks like an ugly hack.
