Title: FIXED http://www.magentocommerce.com/bug-tracking/issue/?issue=7419

in the method removeAccents is a parameter to use german replacement for umlauts like öäü.

But this doesn't work, because array_merge destroys the key => value relation in the replace array.

The array union operator doesn't do that.
