Yup.  If this mangling is needed outside of CGObjCGNU, it would be good to take the code that does this mangling and move it somewhere that can be reused.  I don't know if there are any characters that are valid in Objective-C type encoding but aren't valid in Windows PE/COFF symbols, but having a hook to fix them in a single place sounds like a good idea.
