or we can store QCString instead of QString and increase the PCS-version 
number. BDB has problems with unicode characters. it shouldn't be too hard. 
  1) replace QString with QCString in catalog/tag*
  2) replace QString with QCString in cppsupport/cpp_tags.*
  3) ensure we don't store QStrings in cppsupport/tag_creator.*
