tungscit commentedThe issue is caused by encoded request_uri() which lead to non-matching theme switching rule.
For example:
- if the theme switching rule chain includes drupal:path = path/äbc/% >>> exampleTheme
- User access http://www.example.com/path/äbc
- themekey_match_path() try to find a matching rule by using request_uri() to compare with db rul chain value
- request_uri() will return path/%C3%A4bc which of course will never match with db rule chain value
Comment #5
tungscit commentedUsing urldecode before comparing path alias with db path chain value should fix the issue.
Attached is the patch.

mkalkbrennerYou're right. But I'm concerned about backward compatibility. It could be that users already use urlencoded paths in their ThemeKey rules. And there's a difference between urlencode and rawurlencode.
What do you think about this variant of the patch?
