Actually, with most versions of unix, ":set list" only affects white space. It causes tabs to show up as ^I and newlines to be marked with $.
The real problem is that some bytes could have values in the range of 128 to 255 and you may not have an 8 bit data path to your terminal. Depending on the stty settings, the MSB may be a parity bit rather than a data bit. Also not all terminals will display something for non-ascii characters. And a final problem is that, I think, vi balks at attempting to display nulls, although it will count them and display a count at startup time.

HLS(1) General Commands Manual HLS(1)
NAME
hls - list files in an HFS directory
SYNOPSIS
hls [options] [hfs-path ...]
DESCRIPTION
hls lists files and directories contained in an HFS volume. If one or more arguments are given, each specified file or directory is shown;
otherwise, the contents of the current working directory are shown.
OPTIONS
-1 Output is formatted such that each entry appears on a single line. This is the default when stdout is not a terminal.
-a All files and directories are shown, including "invisible" files, as would be perceived by the Macintosh Finder. Normally invisible
files are omitted from directory listings.
-b Special characters are displayed in an escaped backslash notation. Normally special or non-printable characters in filenames are
replaced by a question mark (?).
-c Sort and display entries by their creation date, rather than their modification date.
-d List directory entries themselves rather than their contents. Normally the contents are shown for named directories on the command-
line.
-f Do not sort directory contents; list them in the order they appear in the directory. This option effectively enables -a and -U and
disables -l, -s, and -t.
-i Show the catalog IDs for each entry. Every file and directory on an HFS volume has a unique catalog ID.
-l Display entries in long format. This format shows the entry type ("d" for directory or "f" for file), flags ("i" for invisible),
file type and creator (four-character strings for files only), size (number of directory sub-contents or file resource and data
bytes, respectively), date of last modification (or creation, with -c flag), and pathname. Macintosh "locked" files are indicated by
"F" in place of "f".
-m Display entries in a continuous format separated by commas.
-q Replace special and non-printable characters in displayed filenames with question marks (?). This is the default when stdout is con-
nected to a terminal.
-r Sort entries in reverse order before displaying.
-s Show the file size for each entry in 1K block units. The size includes blocks used for both data and resource forks.
-t Sort and display entries by time. Normally files will be sorted by name. This option uses the last modification date to sort unless
-c is also specified.
-x Display entries in column format like -C, but sorted horizontally into rows rather than columns.
-w width
Format output lines suitable for display in the given width. Normally the width will be determined from your terminal, from the
environment variable COLUMNS, or from a default value of 80.
-C Display entries in column format with entries sorted vertically. This is the default output format when stdout is connected to a
terminal.
-F Cause certain output filenames to be followed by a single-character flag indicating the nature of the entry; directories are fol-
lowed by a colon (:) and executable Macintosh applications are followed by an asterisk (*).
-N Cause all filenames to be output verbatim without any escaping or question-mark substitution.
-Q Cause all filenames to be enclosed within double-quotes (") and special/non-printable characters to be properly escaped.
-R For each directory that is encountered in a listing, recursively descend into and display its contents.
-S Sort and display entries by size. For files, the combined resource and data lengths are used to compute a file's size.
-U Do not sort directory contents; list them in the order they appear in the directory. On HFS volumes, this is usually an alphabetical
case-insensitive ordering, although there are some idiosyncrasies to the Macintosh implementation of ordering. This option does not
affect -a, -l, or -s.
