It seems all current browsers (Firefox 39, Chromium 31 and Opera 30) have no issue with our url encoded single quote ('), but Opera 12 falls into a redirect loop and finally displays a blank page. I know Opera 12.16 is a browser which is becoming old, I’m accustomed to.
In the Opera Developer Tools (Dragonfly):
- Opera fetches URL: https://fr.wikipedia.org/wiki/O'Hare_Branch
- MediaWiki server redirects to: https://fr.wikipedia.org/wiki/O%27Hare_Branch
- Opera enforces the url to have an unencoded single quote and before fetching from network rewrites the url as: https://fr.wikipedia.org/wiki/O'Hare_Branch
- Back to #1.
For now I have not searched if the single quote has the same status in RFC 3986 than the tilde of T105265.
