Normalize directory entries in Encoding wrapper
Directory entry file names are now normalized in getMetaData(),
getDirectoryContents() and opendir().
This makes the scanner work properly as it assumes pre-normalized names.
In case the names were not normalized, the scanner will now skip the
entries and display a warning when applicable.
