REVISION SUMMARY
  Handling projects where metainfo.yaml are then found in paths with
  non-ascii chars still needs a separate, more complicated fix.
  This patch should though at least unbreak the run of kapidox on api.kde.org

TEST PLAN
  Added a subdir "testü" to kcoreaddons, with the patch python2 kapidox does
  no longer fail.
