strange Dos metacharacters

I have a text file of .srt subtitles downloaded in dos fornat,
and want to convert to unix text style.  I have no problems
removing the ^M character with sed (using ctrl-V ctrl-M).

But every other character in the file is this "^@" :

^@m^@a^@ ^@p^@i^@c^@c^@o^@l^@o^@ ^@t^@a^@g^@l^@i^@o^@.^@^@

I can't seem to produce this control sequence on the keyboard.
Does anyone know what it is?

Cheers,
Simon

Looks as if you have a UTF-16 encoded file as opposed to ASCII, Latin1,
or UTF-8.  You'll need something like iconv to convert it.

On my slackware xterm bash:

$ for i in $(seq 0 255)
> do printf "$i \x`printf %x $i`\n"
> done|cat -v|grep @
0 ^@
64 @
128 M-^@
192 M-@
$
$ echo -e "\x00"|cat -v
^@
$
$ echo -e "\000"|cat -v
^@
$
$ echo -e "m\000a\rc"|cat -v
m^@a^Mc
$ echo -e "m\000a\rc"|tr -d '\000\r'|cat -v

Thanks for the tip, that was exactly the problem.

The _file_ utility (which I just discovered) identified it  as
UTF-16, and iconv converted easily to ASCII.

(Turns out the subtitles are in Italian though.)
