Problem with german umlauts after upgrade to 3.9.1

  • Hi @ll!

    I’ve got some kind of weird problem. I’ve upgraded my installation of wordpress from 3.8.3 to 3.9.1 via the automatic update. After that I’ve got problems with german umlauts (?, ?, ü). They are no longer proper displayed.

    I’m using the CFDB plugin on my website (it’s located in my intranet … so I can’t give you a URL to check). In Wordpres 3.8.3 everything is fine. If someone posts f.e. the city name “Düsseldorf” it is properly displayed on my site. With WordPress 3.9.1 (or 3.9 – I’ve checked both versions) the city name isn’t displayed. The table space where the city name should be displayed is empty!

    I’ve already discussed this problem with the plugin author of the CFDB plugin without success. He can’t reproduce my error.

    What I’ve done so far:

    – checked the collation of the table before and after the upgrade (latin1_swedish_ci)
    – disabled all plugins and activated them one by one … without luck
    – checked the setting <meta charset="utf-8" /> in the header.php of my theme … it’s still there like it was before

    Any suggestions to this problem?

    Thanks in advance

    – Markus

  • If you are going to try and correct the issues in the plugin yourself, can I suggest that you try posting in the Hacks sub-forum?

    I’ll do that if I someone can confirm that the problem is caused by the plugin itself and not by changes in the wordpress core.

    Please don’t understand me wrong. I try to find the cause of my problem.

    And I think I have to improve my slightly rusty english. Sorry for that.

    Many thanks for your support, esmi!

    And just a few moments ago I think I find the cause of the problem: please have a look at wp-db.php in the wp-includes folder. Around line 590 there is a check on the php-version which then sets use_mysqli to true. If I change this value (the value of the checked php-version) from 5.5 to 7.0 my problem is solved. All german umlauts are then properly displayed.

    I’ve found that by comparing the wp-db.php from version 3.8.3 with the new one in 3.9.1.

    Is this a bug or a feature that german umlauts aren’t properly displayed if the wp-db.php script uses mysqli???
