Broken encoding for german umlauts in search-builder
The select-field-options in the search-builder have broken umlauts if you use german as default-language.
To reproduce this issue just take a fresh CiviCRM-Installation, select "german" as default-language, open the search-builder and select "Kontakte" as record-type. As you see the umlauts of the options of the field-selection are broken.
This was tested with version 5.5.3 and 5.6.0
