This is not 'some unreadable unicode stuff' it is an Objective-C type 
encoding.  You will see errors like this if either libProjectCenter.so 
contains a source file that references a @private or @package ivar of 
NSView, or if it references a @public / @protected ivar with the wrong 
type.

The latter can happen if you compiled against the wrong version of the 
headers.
