It does. RTFS. (-8

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

/*
* The maximum allowed length for a file name.
*/
#define MAXIMUM_FILE_NAME_LENGTH 255

/*
* Possible namespaces for filenames in ntfs (8-bit).
*/
typedef enum {
FILE_NAME_POSIX = 0x00,
/* This is the largest namespace. It is case sensitive and
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. */
FILE_NAME_WIN32 = 0x01,
/* The standard WinNT/2k NTFS long filenames. Case
insensitive.
All Unicode chars except: '\0', '"', '*', '/', ':', '<',
'>', '?', '\' and '|'. Further, names cannot end with a '.'
or a space. */
FILE_NAME_DOS = 0x02,
/* The standard DOS filenames (8.3 format). Uppercase only.
All 8-bit characters greater space, except: '"', '*', '+',
',', '/', ':', ';', '<', '=', '>', '?' and '\'. */
FILE_NAME_WIN32_AND_DOS = 0x03,
/* 3 means that both the Win32 and the DOS filenames are
identical and hence have been saved in this single filename
record. */
} __attribute__ ((__packed__)) FILE_NAME_TYPE_FLAGS;

The whole of layout.h can be viewed here (link to view of CVS):
