REVISION SUMMARY
  commit 6a18528 <https://phabricator.kde.org/R237:6a185285ae44ed182dbab9206b9092f78c7d3714> introduced escaping of bytes >= 127 to ensure that
  KConfig files are valid UTF8.
  The simplistic approach with a cutoff results in many escaped bytes
  where it is not required. Especially non-western configuration files
  would have many escapes.
  
  This commit fixes that by only escaping bytes that are not valid UTF8.
