The operative part seems to be;
Could not find a storyboard named '<strange character>' in bundle NSBundle...
It most likely means that the name set for your main storyboard is messed up (I can repeat the exact symptoms on a new project, just changing the storyboard name to a non existing one).
Start by checking that the correct story board name is set as "Main Storyboard" (click the project, then the Summary tab, iPhone should be visible, iPad is farther down). When that is set correctly, a clean/rebuild (as Alex Blundell pointed out in the comments) is required to rebuild with the correct name.
