I’ve recently migrated a decent sized site from Drupal to WordPress and as part of it, I’ve migrated the permalink structure for SEO purposes.
The problem now is that special characters do not seem to be supported in permalinks the way they were in Drupal.
This works fine in Drupal. In WordPress, it produces a 404. There are about 9,000 posts, so doing anything manually is out of the question. Also, I would rather not replace all the special characters in the permalinks for SEO purposes (or I’m going to have to create a forwarding table, which I suppose would be the last resort).
So the question is: Is there any way to force WordPress to allow special characters in permalinks without 404ing, the way Drupal allows them?
Thank you very much for any help you can provide.
