steps to replicate the issue (include links if applicable):
- open https://en.wikisource.org/wiki/Trump_v._Internal_Revenue_Service_settlement_agreement (or https://en.wikisource.org/wiki/Order_establishing_the_Anti-Weaponization_Fund or https://en.wikisource.org/wiki/Order_barring_the_Internal_Revenue_Service_from_investigating_Trump_and_his_family)
- click a page link (the little number between the square brackets on the left)
what happens?:
"bad title" error: "The requested page title contains invalid characters: "%3D"."
what should have happened instead?:
open the page link
i'm about 80% sure this is caused by the equals sign being parsed into "%3D" in the url, and then that is erroneously parsed into "%253D"; if you change "%253D" into "%3D", the link works
