    Didn't try (because I haven't such filenames), but wonder how it
would be possible.

  1) it is impossible in Linux to modify a file without access
permission, and permissions are not associated to the inode but to the
whole directory tree above.

  2) there isn't a function in the C library which permits to change
the name of a file (or open it), except by giving its whole pathname.
Eg. it's not possible to open it from its directory entry.

  Therefore I wonder how 'find' would do, unless fopen() accepts the
pathological name, which I doubt of.

  Sorry to be so negative. Mount options suggested by others are
probably a better idea.
