In akonadi console I've created a new Nepomuk Tags (Virtual Folders) resource.

This resource contains many tags (most of them seems to be empty), but the issue here: it does not handle umlauts (äöüá etc.). At least these glyphs are replaced by the question mark with black background in the akonadiconsole Browser.

My locale is de_DE.UTF-8.

Reproducible: Always

Steps to Reproduce:
1. Create some things that nepmuk will recognize with umlauts
2. Create a Nepomuk Tags resource
3. Open the Browser tab in akonadiconsole

Actual Results:  
Umlauts are replaced by default character

Expected Results:  
Umlauts are shown
