Try ...
ls -lia
... and then, note the inode number in left, your left that is, most
column which will be used in ...
find . -inum <noted inode number> -type d -print0 \

Yes, using '//' is same as '/' in some shells. Try this in a sh-like
shell (sh, bash [23], ksh93) ...
for shell in sh csh tcsh bash ksh93 blah
do
shell=$(which $shell)
[ -z "$shell" ] && continue
echo "checking shell $shell"
$shell -c 'cd //usr///local/////bin && echo $PWD && pwd'
echo
done
... here is what i get in some shells (bash is bash 3) ...
checking shell /bin/bash
//usr/local/bin
//usr/local/bin
checking shell /usr/local/bin/ksh93
/usr/local/bin
/usr/local/bin
