This would at least create incompatibilities with long filenames.
ISO-8859-1 is the low 8 bits of UNICODE and if I use a ISO-8859-1
coded filename I am currently able to have up to 255 ISO-8859-1
characters in a filename.
After e.g. UFS is converted to UTF-8, the max file name length depends
on the content of a filename and may be reduced to only 127 ISO-8859-1
characters. As a result, you may be unable to restore a backup.
