You can use a hex-dump utility to see what characters are actually in
the file. On unix, I often use od. But if I've got the data in a Perl
string, I'll just use Perl:
print "####", unpack("H*", $data), "\n"; # debug hex dump
I've already tried chomp and s/\^\@// Neither work.
You tried chomp? Did you also try sqrt? :-)
Even though that character looks like ^@ in a program such as vi,
that's not one of the ways Perl uses for writing special characters. I
suspect that this one is the NUL character, and vi is calling it
"control-@" (which makes some sense from the ASCII chart). If that's
it, it's character zero, which can look as simple as "\0".
s/\0+//g; # strip NUL characters
Good luck with it!
