Hi,
Some days ago i tried to fix the collations of my Drupal (MySQL) website. But it did not work for several reasons.
I attach a patch that solved the problems for me:
Closed: outdated
1.4
Code
Not all content is available!
It's likely this issue predates Contrib.social: some issue and comment data are missing.
I'm closing this since Drupal 7 is now unsupported and there will be no more development on the Drupal 7 branch of Collation Fixer either.
Thank you for taking the time and effort in reporting this issue, even though it never got resolved.
