FACLs are normally indicated by a + at the end of the permissions.

  $ ls -ld .
  drwxr-xr-x 2 sweh sweh 4096 Jul 31 06:38 ./
  
  $ setfacl -m user:named:- .
  
  $ ls -ld .
  drwxr-xr-x+ 2 sweh sweh 4096 Jul 31 06:38 ./
[note the +]

  $ getfacl .
  # file: .
  # owner: sweh
  # group: sweh
  user::rwx
  user:named:---
  group::r-x
  mask::r-x
  other::r-x

Attributes ("chattr") don't get shown by any special character
  $ ls -ld .
  drwxr-xr-x 2 sweh sweh 4096 Jul 31 06:41 ./

  $ chattr +d .

  $ ls -ld .
  drwxr-xr-x 2 sweh sweh 4096 Jul 31 06:41 ./

  $ lsattr -ad .
  ------d------ .
