It does. RTFS. (-8

 From ntfs-driver-tng/linux/fs/ntfs/layout.h:

  */
#define MAXIMUM_FILE_NAME_LENGTH 255

/*
  * Possible namespaces for filenames in ntfs (8-bit).

                    allows all Unicode characters except for: '\0' and '/'.
                    Beware that in WinNT/2k files which eg have the same name
                    except for their case will not be distinguished by the
                    standard utilities and thus a "del filename" will delete
                    both "filename" and "fileName" without warning. */
