Perhaps I might have figured out what is going on, just someone a bit
more knowledgeable about the table structures to double check me.
page table page_title set to varchar with a collation of UFT-8
on other wikis
page table page_title set to varbinary(255)
Storing the %3F as a ?, could that be the problem because ascii not
uft-8 recognizes %3F
This wiki is much older and has been upgraded from original 1.14 to
1.15, then 1.17, then 1.19. I ran the upgrade script after each upgrade.
