Description

Why

What

add a special language code called ?uselang=x-double-escape or similar, that changes every message to <test>key-name</test>. then the user can look for <test>key-name</test> to indicate a key that needs fixing.

Notes

I got the idea when reviewing https://gerrit.wikimedia.org/r/c/mediawiki/extensions/SecurePoll/+/1168241, which fixes a double escape that was happening due to a lack of ->text()
this would be similar to T340201: Use custom language code to find i18n XSS issues
we could bundle this into the existing $wgUseXssLanguage setting instead of making a new setting

What would the advantage be of using this instead of x-xss, which already contains angle brackets in a slightly different format?

Ah, you're right. The existing uselang=x-xss would work just fine here.

Good thinking. Closing.
