TYPO3 Core

If users enter a serachword in the searchfield of indexed_search the searchstring is entered in the table index_stat_search. all the words containing the "searchphrase" are somehow split and written in the table index_stat_word.

if you enter german umlaut like äüö the table index_stat_word is filled with some wrong characters. the table index_stat_search is filled correctly.
