I've run a process to find pages in the database with
invalid/inaccessible titles and rename them. The ones with invalid
characters or that conflicted with existing normalized forms have had
'Broken/' prefixed to their names, and are listed at
[[Special:Prefixindex/Broken/]] on each wiki.
These are mostly leftover from old software bugs since fixed, and a lot
of them are redirects created by page moves to corrected titles and can
now be discarded.
