TYPO3 Core

On version 8.7.9 looks all fine. All my test cases where found with the search module on top right.

Ok, sorry. Problem just exists on my localhost. In same TYPO3 system, but different server, search works.

@Sven Burkert thank you for your quick answer; so do you think that this issue can be closed?

It's still strange and perhaps a TYPO3 bug, that live search on top right doesn't work with umlauts on my localhost and search in list module does, but if you think, it's the fault of my localhost, please close this ticket.

@Sven Burkert could you add more information on how to reproduce your issue? Please add as much info as possible about your localhost system and configuration.

It is hard to decide wether it is an actual bug or a local misconfiguration; I have tried a little test on my local machine

- TYPO3 8.7.9
- MAMP environment
- PHP 7.1.8
- MySQL 5.6.35
- utf8_general_ci database collation

I created a page whose title contain the letters "ä, ö, ß" and a page content with the same letter and the upper right corner search was able to find both.

Should I perform a different test?

I've broken it down to line 366 in file typo3/sysext/backend/Classes/Search/LiveSearch/LiveSearch.php:

$queryBuilder->createNamedParameter(strtolower($like), \PDO::PARAM_STR)

Parameter "$like" is here e.g. "%testä%", but "strtolower($like)" results in "%test�%".

When using function "mb_strtolower" live search works.
$GLOBALS['TYPO3_CONF_VARS']['SYS']['systemLocale'] is not set, OS is Windows 7, locale for LC_CTYPE is "German_Germany.1252".

Patch set 1 for branch TYPO3_8-7 of project Packages/TYPO3.CMS has been pushed to the review server.
