I created a Drupal website some years ago and everything was working well until now.
But since yesterday (when the client came back to me), the Pathauto module is now replacing all accented characters by quoting marks in URL aliases.
For example for this node, the URL alias was correct and it was updated.
But now, if I check the option "Generate automatic URL alias", then the "é" character is replaced by ??, as you can see there.
Any idea why this is occurring? How can I fix that?
