The way that I've seen is a mapping of special characters, one way or
the other. So the Mac side sees '/' but the unix side sees %100 (or=20
whatever..)
Also to note, HFS/HFS+ record case, but is not case sensitive, hence
one can not archive the NetBSD cvs source hierarchy on an HFS volume,
last time I checked there were about 200 files which differed only by=20
case.
find . -print | tr "[:upper:]" "[:lower:]" | sort >/tmp/list
find . -print | tr "[:upper:]" "[:lower:]" | sort | uniq >/tmp/uniqlist
diff list uniqlist
if there are no files differing only by case, the diff should produce no
differences...
MS systems have the same case recording but otherwise insensitive
attribute as well...
